American Football 101 |OT| - Schemes, breakdown and professorial talk

ihXcPWS.jpg

(THREAD IS UNDER CONSTRUCTION)

I'll be updating this throughout the day and the week with actual graphics that are being worked on so bear with me. For now I wanted to get the thread up with the content/resources I've gathered. If anyone wants to lend a hand in that department, please feel free to contact me via PM. I'm all for prettying this up!

jjGo70cdrFoGY.jpg


The purpose of this thread is to discuss American Football at a high level. This includes breaking down film, discussing different schemes employed and hopefully helping to educate those that are looking to know more. This is a "one all" discussion thread. Meaning that the discussion is not only limited to the NFL. College and high school football are completely fair game here. Draft analysis is also welcome.

This is NOT the place to talk about weekly games, your specific team needs, news on who your team signed etc. That belongs in the weekly NFL or general College football threads.

To summarize what's acceptable:
- Novice or high level questions/discussion about football.

- Breakdown of film. All-22 is now available from Game Rewind on NFL.com which gives us unprecedented access to the very same film coaches use to break their opponents down.

- Discussion on schemes. Why use them? When is it appropriate to employ a nickel defense? Why would I want to use an option route on offense?

- Discussion of said schemes on a per team basis. If you're an Atlanta Falcons fan and want to talk about why the defense failed against the 49'ers this past weekend - don't just say "the defensive plan sucked!", tell us why! Possibly even illustrate it using film breakdown.

- Draft analysis is welcome as noted. If you want to do a scouting report on a certain player or discuss them more in-depth this is the place to do it.

To summarize what's unacceptable:

- Trolling novice users for not knowing certain things. If you know more, then help to educate. If you're here to be general troll then move on. This isn't the place for you.

- Weekly game conversations should be in their respective threads. Calls of TAINT!, you people, Josh Freeman Taco Bell jokes and all of the other fun memes that are used in the NFL threads can stay there. This isn't the place for them. Nothing wrong with a little light ribbing here and there and we certainly want to keep this fun but the goal here is for a more serious Football conversation.

- NFL/College news items. Post them in the weekly or college thread. It's nice that the Eagles have a new head coach. This isn't the place to talk about it!

Audible - A play called by the quarterback at the line of scrimmage to make a change from the play that was called in the huddle.

Ball control - A strategy that is based on low-risk plays in an effort to avoid losing possession of the ball; examples of when a ball-control strategy would be used include when a team is in the red zone and when a team is protecting a lead late in a game.

Backward pass - A pass thrown backward. Also called "onside pass" in Canadian football. There is no limit to the number of backward passes or where they may be thrown from. Sometimes referred to as a "lateral," which specifically refers to a pass thrown with no motion toward either end zone.

Blitz - A defensive maneuver in which one or more linebackers or defensive backs, who normally remain behind the line of scrimmage, instead charge into the opponents' backfield. However, in the 3-4 defense, one linebacker typically rushes the passer with the three down linemen. This is not considered a blitz. If an additional linebacker is sent, bringing the total number of rushers to five, it is a blitz.

Block - The act of one player obstructing another player with his body, either to push him back or to prevent him from moving beyond the blocker. Some types of blocks include: a run block, where the blocker pushes a defensive player back and away from the ball carrier; a pass block, where a blocker protects a player by moving laterally and backwards to slow or halt an incoming pass rusher; a cut block; a zone block, which is any block executed in a zone blocking scheme; a trap block; a pull block; a screen block, which is a kind of pass block; and a double-team block, where two blockers simultaneously block one player.

Blocking back - Used to describe a running back who is assigned to block. It describes either an assignment for a single play or the back's primary function throughout his career, such as when describing a fullback who is particularly skilled at blocking. Also an early term for quarterback.

Bootleg - An offensive play predicated upon misdirection in which the quarterback pretends to hand the ball to another player, and then carries the ball in the opposite direction of the supposed ballcarrier with the intent of either passing or running (sometimes the quarterback has the option of doing either). A naked bootleg is a risky variation of this play when the quarterback has no blockers pulling out with him. Contrast with scramble, sneak, and draw.

The Box - An area on the defensive side of the ball, directly opposite the offensive linemen and about 5 yards deep; having 8 players in the box means bringing in a defensive back, normally the strong safety, to help stop the offensive team's running game.

Bubble screen - A type of screen pass where the quarterback takes the snap and immediately throws to a wide receiver lined up to the far right or left of the center. The receiver catches the ball, and then turns to run downfield.

Chop block - Similar to a cut block in which one offensive player blocks a defensive player below the knees and another blocks him above the waist. It is illegal to block low if a team mate is already engaged with the defensive player blocking high to prevent knee and ankle injuries.

Checkdown - The checkdown pass is when the quarterback has to complete a short pass to a running back or tight end as a last resort to avoid a sack. Handling a checkdown situation is for a running back to catch this short pass, then use his speed, agility and power to run for extra yardage.

Clipping - An illegal block in which the victim is blocked from the back and at or below the waist; the penalty is 15 yards. Originally, clipping was defined as any block from the back, but is now restricted to blocks at or below the waist. Other blocks from the back are now punished with 10-yard penalties.

Coffin corner - The corner of the field of play between the end zone and the 10 yard line. A punter, if he is close enough, will often attempt to kick the ball out of bounds close to the receiving team's goal line and pin them back near their own end zone.

Comeback route - A receiver or tight end route where the player runs straight upfield a specified number of yards (could be a short or medium route), plants hard, and turns and runs back towards the sideline at a 45 degree angle. Often confusingly named, a wide receiver doesn't come back towards the quarterback, instead he tries to catch the ball and guarantee getting out of bounds.

Hook or Dig route - The buttonhook route is when a receiver runs straight upfield a certain distance and then plants hard and runs straight back towards the quarterback. Often simply called a hook route or a dig route. In some cases, a dig route is considered a very long buttonhook, such as 15+ yards downfield. Hence the receiver must dig his cleats in hard to stop and come back at the quarterback after running so far and fast.

Post pattern - A passing route in which the receiver sprints 8 to 10 yards, fakes a look back at the Quarterback, then sprints deep at an angle toward the middle of the field; the opposite pattern is the flag route. It is called a post pattern because the middle of the field is where the goal posts are found.

Slant - A receiver route. In the slant route, a receiver runs straight upfield a few yards, plants his outside foot hard while in full stride, and turns 45 degrees towards the quarterback. A staple of the West Coast Offense (WCO) and the player may go as little as 2 yards or as many as 6 yards before moving inside for the pass. Variations include the quick slant in which the player plants and turns at the snap instead of running ahead first and the Slow or Zone route, in which the receiver runs 10 to 15 yards downfield to get behind the linebackers before turning.

Wheel route - A pass route in which the receiver, often a running back, travels parallel along the line of scrimmage and then takes off up the field.

*All WR Routers can be seen here:

Counter - A running play in which the running back will take a step in the apparent direction of the play (i.e., the direction the line is moving), only to get the handoff in the other direction. Weak side linemen will sometimes pull and lead the back downfield (sometimes called a counter trap), but not necessarily. The play is designed to get the defense to flow away from the action for a few steps as they follow the linemen, allowing more room for the running back.

Crackback block - An illegal block delivered below the opponent's waist by an offensive player who had left the area of close line play and then returned to it, or was not within it at the snap. The term is also used to describe a legal block (delivered from the front, or from the side with the offensive player's helmet in front of the blocked player) by a wide receiver on a player who lined up inside of him.

Cut - A sharp change of direction by a running player. Also called a cutback.

Cut block - A blocking technique in which offensive linemen, and sometimes other blockers, block legally below the waist (i.e., from the front of the defensive player) in an attempt to bring the defenders to ground, making them unable to pursue a running back for the short time needed for the back to find a gap in the defense.

Dime back - The second extra, or sixth total, defensive back. Named because a dime has the same value as two nickels (see Nickel Back)

Direct snap - A play in which the ball is passed directly to the presumed ball carrier by the center. Contrast with an indirect snap play in which the ball is first handed to the quarterback, who will then pass or hand it to the eventual ball carrier. Also used to refer to formations that use a direct snap, such as the single wing.

Dive - A play in which the ball is handed off to the running back, who attacks the middle of the offensive formation (between the OG). This play is part of the Triple option strategy.

Double reverse - A play in which the ball reverses direction twice behind the line of scrimmage; this is usually accomplished by means of two or three hand-offs, each hand-off going in an opposite direction as the previous one. Such a play is extremely infrequent in football. Some people confuse the double reverse with a reverse, which is a play with two hand-offs instead of three.

Draw play - A play in which the quarterback drops back as if to pass, then hands off to a running back or runs with the ball himself.

End around - A play, often confused with a reverse, where the quarterback hands the ball off to a wide receiver. The receiver motions/moves into the backfield as the ball is snapped to take the handoff and runs around the opposite end from where he lined up.

Flat - An area on the field between the line of scrimmage and 10 yards into the defensive backfield, and within 15 yards of the sideline. Running backs often run pass routes to the flat when they are the safety valve receiver.

Two-point stance - The two-point variation is the most upright stance. The two-point is used by offensive linemen to facilitate better pass blocking because it increases their initial field of vision and gives more reaction time (to stay in front of a rushing player). Consequently, it is usually only used in a situation that will require passing. Some defensive linemen employ this stance to pass rush because they naturally obtain more quickness and agility out of it (particularly the defensive ends).

Three-point stance - The most common variation is the three-point stance. The purpose of this stance is to give the player leverage and allow more of their legs' power to be used. This is the offensive lineman's most used stance. It allows them to easily stay low and move in any direction at the snap of the ball. The interior defensive lineman use this stance for the same reason; however, it is usually slightly adjusted.

Four-point stance - The least common variation is the four-point stance. This stance is used for maximum explosion and leverage in one direction (straight ahead of the player). Offensive linemen will typically only use it if they need to force the line forward only inches. Interior defensive lineman will use it to keep this push from happening.

Hands team - A group of players, mostly wide receivers, that are responsible for recovering an onside kick. They line up as close as possible to the ten-yard neutral zone and their goal is to recover the ball immediately after, but only if, the ball crosses out of the neutral zone.

Hard count - A strategy commonly used by offenses to convert on fourth down and less than five yards to go. An offense will take the full time on the play clock with the quarterback utilizing an irregular, accented (thus, the term "hard") cadence for the snap count in the hope that the defense will jump offside, giving the offense the five yards needed to convert the first down. However, if the defense does not go offside, the offense will take a five-yard penalty for delay of game and punt the ball away.

I formation - A formation that includes a fullback and tailback lined up directly behind the quarterback while the quarterback is under center. By definition, the fullback lines up in front of the tailback. Several variations on this backfield formation exist, including the "Offset I" (in which the fullback lines up out of line to the left or right of the quarterback and halfback; also known as the strong or weak I depending on which direction the fullback is positioned), the "Maryland I" and "Power I" (in which an additional fullback is added to the backfield, either next to in the Power I's case or in front of in the Maryland I's case, the fullback).

iMHXgDsNvdE0.PNG


Icing the kicker - When a team calls time out just before the kicker has the ball snapped. A team is limited to calling one time-out on any given play (thus a team cannot repeatedly call all of its time-outs to prevent the game from continuing, or else a delay of game penalty or, more rarely, a palpably unfair act penalty is imposed).

Jumbo - An offensive package which includes two tight ends, a full back and a half back. Similar to heavy jumbo, in which either the half back or the fullback is replaced by another tight end. In a goal line formation, Miami package, often one or more of the "tight ends" is actually a linebacker (the New England Patriots used Mike Vrabel this way - he has 11 career regular season TDs) or offensive lineman. In the NFL, such a player must report in as an eligible receiver because a lineman or linebacker would not generally wear an eligible number.

Man-to-man coverage - A defense in which all players in pass coverage, typically linebackers and defensive backs, cover a specific player. Pure man coverage is very rare; defenses typically mix man and zone coverage.

Max protect - A modification used on pass plays (usually combined with a shotgun formation) which keeps the tight end and both backs in behind the line of scrimmage to pass protect rather than run a pass route. This is used in obvious blitzing situations to give the quarterback "maximum protection" in the pocket. Although good for holding off a blitz, it leaves the quarterback with only two receivers to throw to (and therefore only two players for the secondary to defend).

Mike (MLB) - The middle linebacker in 4-3 formation. In the 3-4 formation Mike is the Interior Linebacker (ILB) that plays on the strong side of the formation. Mike has the responsibility to defend the interior gaps and the Curl Zone. Mike is the leader of the defense and has to be as bright as a Quarterback because often he calls the audibles on defense.

Motion - The ordered movement of eligible receivers prior to the snap. Motion can be used to gain mismatches, i.e. physical advantages against specific defensive personnel, e.g. a fast wide receiver defended by a slower linebacker. Another use for motion is to enhance the pre-snap read of the defensive coverage, e.g. motioning a receiver from one side of the formation to the other may help in identifying zone versus man coverage. Generally, if the coverage is man the receiver's defender will follow him across the formation and if it is zone coverage the defenders will exchange responsibilities by shifting or bumping over.

Neutral Zone - The region between the lines of scrimmage or between the free kick restraining lines

Nickel back - An extra, or fifth, defensive back. Named after the coin, worth five cents.

Run or option run - Usually, a type of play in which the quarterback has the option of handing off, keeping, or laterally passing to one or more backs. Often described by a type of formation or play action, such as triple option, veer option, or counter option. Teams running option plays often specialize in them. Less often, a play in which a back may either pass or run.

Pancake block - Pancake block; sometimes shortened to cake; slang for a particularly effective block where the player being blocked is pushed onto the ground by a blocker, metaphorically "flattening" the opposing defender into a pancake. This is usually performed by an offensive lineman, tight end, or fullback, and is considered an ideal block, designed to completely eliminate the defender from the play for several seconds, or for as much time as it takes said defender to get back to his feet. While not an official statistic, offensive linemen often keep track of the number of pancakes they have made, and successfully performing this block is termed pancaking or caking an opponent.

Peel-back block - An action where an offensive player blocks a defender who is moving back toward the direction of his own end zone; they are illegal below the waist and from either the back or the side.

Pick-six - An interception ("pick") that is returned to the passing team's end zone for a touchdown ("six").

Play action - A tactic in which the quarterback fakes either a handoff or a throw in order to draw the defense away from the intended offensive method

Pistol formation - A hybrid version of the shotgun in which the quarterback lines up about 3 yards behind the center and the running back lines up directly behind the quarterback.

i3GcJdWowZdhx.png


Pocket - An area on the offensive side of the line of scrimmage, where the offensive linemen attempt to prevent the defensive players from reaching the quarterback during passing plays.

Prevent defense - A defensive strategy that utilizes deep zone coverage in order to prevent a big pass play from happening downfield, usually at the expense of giving up yards at shorter distances. Often used against Hail Mary plays, or at the end of the game when the defending team is protecting a lead.

Pulling - Pulling blocker; an offensive lineman who, instead of blocking the player in front of him, steps back from the line (pulls away from the line) and runs to block a defender, usually in a trap or sweep play.

Pro set - Offensive formation using two backs, lined up side-by-side 2-3 yards behind the quarterback, with one on either side of the quarterback.

iv3Urc1EmZwZd.png


Quarter defense - Defensive formation with seven defensive backs, three down linemen and one linebacker.

Reverse - An offensive play in which a running back carries the ball toward one side of the field but hands or tosses the ball to a teammate (almost exclusively a wide receiver) who is running in the opposite direction. This is slightly different from an end around, in which the ball is handed off directly to a wide receiver (usually the man in motion), so the direction of the play never reverses.

Rover - A hybrid safety that has duel responsibilities as a defensive back and a linebacker. This is more commonly seen in college football more so than NFL, CFL, or AFL football. A perfect example this in use is in West Virginia's or Air Forces's 3-3-5 schemes.

Run and shoot - An offensive philosophy designed to force the defense to show its hand prior to the snap of the ball by splitting up receivers and sending them in motion. Receivers run patterns based on the play of the defenders, rather than a predetermined plan. Also known as 'Run & Gun'.

Run out of the gun - Running the ball out of the shotgun formation, which is primarily a pass formation.

----------------------------------------------------------------------------

----------------------------------------------------------------------------

Sam - The strong side outside linebacker

Scatback - A running back that is generally very fast, and good at juking and making defenders miss as opposed to running them over on purpose like a 'power' back.

Screen pass - A short forward pass to a receiver who has blockers in front of him. The receiver in this play is usually a running back, although wide receiver and tight end screens are also used. Although they are both called screen passes, the wide receiver screen and the running back screen are used for very different reasons. In the case of a running back screen, the play is designed to allow the pass rushers by the offensive linemen, leaving the defender out of position to make a play.

The play is usually employed to defuse the pass rush in the case of a running back screen. The Wide Receiver screen is a much faster developing play, designed to catch the defense off guard.

Shift - When two or more offensive players move at the same time before the snap. All players who move in a shift must come to a complete stop prior to the snap.

Shooting - The action of a linebacker or defensive back to blitz (i.e. shooting the gap)

Shotgun formation - Formation in which offensive team may line up at the start of a play. In this formation, the quarterback receives the snap 5-8 yards behind the center.

i0ZTvSSEg71wx.PNG


Single wing - A diverse set of formations, now out of fashion but highly popular between 1906 and World War II, that typically used an unbalanced line, direct snap, and one wingback.

ibpdm7l8Kg9tEs.jpg


Single wing(ed)-T - A formation with 1 wingback & an adjoining tight end in which the center hands the ball to the quarterback, who holds his hands between the legs of the center.


Slot - The area between a split end and the rest of the offensive line. A pass receiver lined up in the slot at the snap of the ball may be called a slotback or slot receiver.

Strong I - A formation wherein the tailback is lined up deep directly behind the quarterback, and the fullback is lined up offset to the strong side of the formation.

Strong side - The side of the field (left or right) that has the most players, but it depends on the formations of the teams. When a team uses one tight end, the strong side is the side of the field where the tight end lines up. If the offensive package uses no tight end, or more than one tight end, the strong side is the side of the field with the most offensive players on or just behind the line of scrimmage.

Stunt - A tactic used by defensive linemen in which they switch roles in an attempt to get past the blockers. Both defenders will start with power rushes, with the stunting defender getting more of a push. The other lineman will then go around him, ideally using him as a pick to get free from his blocker.

Sweep - A running play in which several blockers lead a running back on a designed play to the outside. Depending on the number of blockers and the design of the play this is sometimes referred to as a "power sweep" or "student-body-right" (or left).

Trap - A basic blocking pattern in which a defensive lineman is allowed past the line of scrimmage, only to be blocked at an angle by a "pulling" lineman. Designed to gain a preferred blocking angle and larger hole in the line.

Trips - A formation in which 3 wide receivers are lined up on the same side of the field, with one on the LOS and usually the others flanking the WR one yard off the LOS (as in Slot or Wing, though only one yard off the WR, each way.

Unbalanced line - Usually refers to an offensive formation which does not have an equal number of linemen on each side of the ball. Done to gain a blocking advantage on one side of the formation; typically one tackle or guard lines up on the other side of the ball. F

Under center - Refers to the quarterback lining up directly behind the center to take the snap.

Weak I - A formation wherein the tailback is lined up deep directly behind the quarterback, and the fullback is lined up offset to the weak side of the formation.

Weak side - When one tight end is used, the side of the field opposite the tight end. In other offensive packages, the side of the field with the fewest offensive players on or just behind the line of scrimmage.

West Coast offense An offensive philosophy that uses short, high-percentage passes as the core of a ball-control offense. Was invented in Cincinnati under coach Paul Brown in the mid 1970s. Is now widely used in the NFL but originally made popular by San Francisco 49ers coach Bill Walsh.

The original west coast offense may have been a term used by Don Coryell, as a Sports Illustrated article accidentally confused Coryell's title with the offense being used by Walsh, thus possibly coining the term. (Coryell's offense was known instead as "Air Coryell" through the 1980s.) The basis of Walsh's offense is to use short routes for receivers, delivering the ball on time and accurately and using short passes to replace runs. It relies heavily on yardage from running after the catch, using many eligible receivers on plays to maximize quarterback options, and spreading the ball to many targets to keep the defense confused.

Wildcat offense - An offensive philosophy that dictates that either a quarterback or a running back can receive a direct snap from the snapper; it is often compared to the single wing. The Wildcat creation is attributed to Gus Malzahn (currently the head coach at Arkansas State University, formerly at Tulsa and Arkansas where he made the formation famous with star backs Felix Jones and Darren McFadden. Coincidentally running back Ronnie Brown of the Miami Dolphins is leading the nation with the Wildcat in 2009 and happens to be a former player at Auburn University).

Will - The weak side linebacker.

Wing back or wingback (WB) - A player position in some offensive formations (Flexbone). Lines up just outside the tight end and one yard off the line of scrimmage. A versatile position that can be used as a receiver, blocker, and/or runner of reverses.

Wishbone - A formation involving three running backs lined up behind the quarterback in the shape of a Y, similar to the shape of a wishbone.

iepGjdGrszKDN.PNG


X-receiver - Used in offensive play calling, usually referring to the split end, the wide receiver who lines up on the line of scrimmage. For example, "Split Right Jet 529 X Post" tells the X-receiver to run a post route.

Y-receiver - A designation used in play calling for the offense's third receiver in a play. This is usually either the slot receiver or a tight end, depending on the play. For example, "Buffalo Right 534 Boot Y Corner" tells the Y-receiver to run a corner route or the offense's primary tight end in a play.

Z-receiver - Used in offensive play calling, usually referring to the flanker, the wide receiver who lines up off the line of scrimmage. For example, "Panther Gun 85 Slant Z Go" tells the Z-receiver to run a go (also called a fly or streak) route.

YAC - 1. Yards After Catch; the amount of yardage gained after initial catch. A quarterback's length of pass is the distance from where the line of scrimmage is, to where the receiver caught the ball. YAC is the distance the ball carrier ran after the initial catch. Screen pass plays boosts YAC effectively due to the short passes, and the receiver has to run to increase yardage.
2. Yards After Contact.

Zone defense - A defense in which players who are in pass coverage cover zones of the field, instead of individual players. Pure zone packages are seldom used; most defenses employ some combination of zone and man coverage.

Zone blitz - A defensive package combining a blitz with zone pass coverage. Allows the defense to choose the blitzer after the offense shows formation and pass coverage requirements, and features unpredictable blitzes from different linebackers and defensive backs. Invented by coach Dick LeBeau.

Zone read - A type of option offense where the quarterback and tail back line up approximately side by side. After the quarterback receives the snap, the two players cross paths and go through the motions of a hand-off. Based upon reading the defensive reaction, the quarterback either completes the handoff or pulls the ball out and runs with it himself.

Power Run - A power play is a running play with two lead blockers; the fullback and the backside offensive guard. A typical scheme for a power push is for the linemen to go down on a man in their gap. The fullback will kick out (block) the last man on the line of scrimmage (an outside linebacker or wide defensive end) and the back side guard will pull and lead up either the guard/tackle hole or the tackle/tight end hole and block the remaining linebacker or defensive back. The principle of this play is to out-number the defense at the point of attack. The tailback must read the guard's block and run off that. Teams at all levels will use this as a base running play in their offense. This play is typically run out of I-formations.

http://en.wikipedia.org/wiki/Power_run

And I wanted to clarify "Power Run" from a "Power Run Game" I feel like analysts mislead the audience nowadays.

Zone Run - Zone running actually has many different variations; an inside zone play or an outside zone play also sometimes wrongly labeled as the stretch (which is in fact a different play). The difference between the three popular zone plays are the aiming point and reads for the ball carrier. While the inside zone has its first landmark around the guards original position, the outside zone aims at the off-tackle area. The stretch usually reads the force defender outside.

Zone Blocking - Zone blocking originates with blocking the first level (defensive line). There are usually two double teams on every zone blocking play (playside and weakside). From each double team, one of the lineman from each will work onto the next level (linebackers). Depending on the flow of the linebackers, either the drive man (inside blocker of double team) or the post man (outside man of the double team) will leave the double team in order to reach the linebacker. If the linebacker reads over the top of the double team (outside) then the post man leaves the double team in order to block the flowing linebacker. If the linebacker comes inside the double team (underneath), the drive/inside double teamer will pick up the backer. This blocking scheme creates cut-back lanes, open pockets of space through which the running back can run. Cut-back lanes are created due to an overcommitment (flow) by the defense and a seal block on the backside by linemen.

http://en.wikipedia.org/wiki/Zone_run

Zone running/blocking has seen a resurgence in the NFL thanks to the success of Shanahan and Kubiak.

----------------------------------------------------------------------------

COMMON PENALTIES

Encroachment - When a defensive player crosses the line of scrimmage and makes contact with an opponent before the ball is snapped. Encroachment is a 5-yard penalty.

False start - When an interior lineman on the offensive team moves prior to the snap of the ball, or when any offensive player makes a quick, abrupt movement prior to the snap of the ball. This is a 5-yard penalty.

Holding (defensive) - When a defensive player tackles or holds an offensive player other than the ball carrier. The penalty is 5 yards and an automatic first down.

Holding (offensive) - When an offensive player uses his hands, arms, or other parts of his body to prevent a defensive player from tackling the ball carrier. The penalty is 10 yards.

Offside - When any part of a players body is beyond the line of scrimmage or free kick line when the ball is put into play. Offside is a 5-yard penalty.

Pass interference - A judgment call made by an official who sees a defensive player make contact with the intended receiver before the ball arrives, thus restricting his opportunity to catch the forward pass. In the NFL, this penalty awards the offensive team the ball at the spot of the foul with an automatic first down. In college, pass interference is a 15-yard penalty and an automatic first down.

This is easily one of the most controversial calls in the NFL. As noted, it's a judgement call by the ref which means enforcement of the penalty is far from consistent. Some refs will penalize even the slightest contact while others will stand idly by as the corner yanks the receiver down by his jersey!

Personal foul - An illegal, flagrant foul considered risky to the health of another player. A personal foul is a 15-yard penalty. (this can include horse collar tackles, helmet to helmet contact to a "defenseless" receiver, player leading with him helmet onto a pile when the whistle has already been blown, tackling/hitting a player who is already out of bounds etc.)

Roughing the kicker - When a defensive player makes any contact with the punter, provided the defensive player hasn’t touched the kicked ball before contact. This is a 15-yard penalty and an automatic first down.

Roughing the passer - When a defensive player makes direct contact with the quarterback after the quarterback has released the ball. This is a 15-yard penalty and an automatic first down.

Intentional Grounding - An incomplete pass thrown by a quarterback toward an area of the field where there is clearly no eligible receiver, usually in a desperate attempt to avoid getting sacked. The penalty usually results in the loss of a down as well as 10 yards or the spot of the pass.

A little more terminology before we dive too deep but we need to cover the various techniques defensive lineman can play. This article does a great job of explaining this in detail:

Three and Five Techniques
(also take a look at the Ultimate Guide to NFL Defense I posted in the resources section. )

A defensive lineman's technique is simply where he lines up in a given defense.The "techniques" are numbered from the inside of the line out (mostly***). The numbers refer to a spot where the center of the defensive lineman's body ends up.

Lining up at a "zero technique" means the DL lines up right over the Center's nose. Moving outward, the even numbers mean lining up directly over an offensive lineman, so 2 is right over the guard, 4 over the tackle, and 6 over the tight end.

The odd numbers mean a DL lines up on the outside shoulder of a lineman. A 1-technique means lining up just to one side of the center, 3 technique on the outside shoulder of a guard, and 5 technique on the outside shoulder of a tackle. Lining up on the outside shoulder of the tight end is actually a 9 technique, and the inside shoulder of the TE is a 7 technique.

Here's the diagram in question:

There's much more to read there in terms of the type of players teams look for to fill those roles but I wanted to establish a baseline before we got too into defensive formations. I'd highly recommend reading both articles before moving on too much.

4-3 Defense - 4–3 defense is a defensive alignment consisting of four down linemen and three linebackers along with four defensive backs. Here's a look at a standard 4-3 alignment:

ib0A4dwjpPlVoY.gif


There are generally two defensive tackles in a standard 4-3 alignment. The technique being played can change but generally a three and a one technique are employed. Some teams do employ the use of a nose tackle (zero or one technique).

Along with the DT's, there are two defensive ends. The defensive end's primary role in the 4–3 defense is to get to the quarterback and create pressure. The 4–3 DE's are the smallest of all of the defensive lineman due to their emphasis of speed over strength. They still need to be strong enough to fight their way past offensive tackles, yet quick enough to pursue the running backs on runs to the outside. Ideal 4–3 defensive ends are athletic and agile and their strength is getting up the field quickly and they usually weigh between 260 and 275 pounds

The middle of the defense is manned by the MLB or the Middle Linebacker. He must be as smart as he is athletic, and is often the defensive leader. The primary responsibility of the MLB is to stop the run, though he will often be asked to fall back in zone coverage in pass protection; man to man pass coverage has him assigned to the fullback typically. The middle linebacker generally calls the plays or calls any audibles on the defensive side of the ball.

There are two outside linebackers in the 4–3. These outside backers are known as the Strong-Side and Weak-Side Linebackers. The Strong-Side, or “Sam” linebacker, is so named because he typically sticks to the strong side of the defense, across from the TE. The “Sam” does his fair share of blitzing, however he also needs to play the run and will usually be relied upon to cover the tight end or potentially a back out of the backfield. The Weak-Side, or “Will” linebacker, will generally play on the weak side and has more freedom than the other LBs, often blitzing the QB or guarding against the screen.

As mentioned above, there are various alignments that are employed with defenses that refer to where the DE's/DT's are lined up on the offensive linemen. These are referred to as either an "Over" defense or an "Under" defense. Here's an example of each:

ibkvJob5pldV65.png


SIDENOTE: You'll notice the A, B, C etc. in between the offensive lineman, right? This refers to the gap in between the center/guard (on either side of the center), guard/tackle and tackle/tight end on the offensive line. So if the defense was calling a "Double A Gap Blitz", they would send two linebackers through the A gap on each side of the center.

The 4-3 defense generally uses four defensive backs. Two of these are safeties, and two of them are cornerbacks. A cornerback's responsibilities vary depending on the type of coverage called. The corners will generally line up 3 to 5 yards off the line of scrimmage, generally trying to "Jam" or interrupt the receivers route within the first 5 yards (commonly referred to as "Press coverage"). A corner will be given one of two ways to defend the pass (with variations that result in more or less the same responsibilities): zone and man-to-man. In zone coverage, the cornerback is responsible for an area on the field. In this case, the corner must always stay downfield of whomever it is covering while still remaining in its zone. Zone is a more relaxed defensive scheme meant to provide more awareness across the defensive secondary while sacrificing tight coverage. As such, the corner in this case would be responsible for making sure nobody gets outside of him, always, or downfield of him, in cases where there is no deep safety help. In man coverage, however, the cornerback is solely responsible for the man across from him, usually the offensive player split farthest out.

The free safety is responsible for reading the offensive plays and covering deep passes. Depending on the defensive call, he may also provide run support. He is positioned 10 to 15 yards behind the line of scrimmage, toward the center of the field. He provides the last line of defense against running backs and receivers who get past the linebackers and cornerbacks. He must be a quick and smart player, capable of making tackles efficiently as well as reading the play and alerting his team of game situations. The strong safety is usually larger than the free safety and is positioned relatively close to the line of scrimmage. He is often an integral part of the run defense, but is also responsible for defending against a pass; especially against passes to the tight-ends.

----------------------------------------------------------------------------

3-4 Defense - The 3–4 defense is a defensive alignment consisting of three down linemen and four linebackers and four defensive backs. Here's a look at a standard 3-4 alignment:

ibsZRTuhwzULFD.gif


The defensive line is made up of a nose tackle (NT) and two defensive ends (DE's). Linemen in 3–4 schemes tend to be larger than their 4–3 counterparts to take up more space and guard more territory along the defensive front. 3–4 defensive ends were usually defensive tackles (DT's) when entering at first. They must be strong at the point of attack and are aligned in most cases head-up on an offensive tackle. First and foremost, they must control run gaps. Size and strength become more of a factor for linemen in 3–4 defenses than in 4–3 defenses because they move primarily within the confines of line play and seldom are in space using athletic ability.

In a 3–4 defense, four linebackers are positioned behind the defensive line. The linebacker unit is made up of two inside linebackers (ILB's) flanked by two outside linebackers (OLB's). The OLB's often line up closer to the line of scrimmage than the ILB's, but may also be positioned at the same depth or deeper in coverage than the ILB's.

Strengths of the 3–4 include speedy ILBs and OLB's in pursuit of backs in run defense and flexibility to use multiple rushers to confuse the quarterback during passing plays without being forced into man-to-man defense on receivers. Most teams try to disrupt the offense's passing attack by rushing four defenders. In a standard 4–3 alignment, these four rushers are usually the four down linemen. But in a 3–4, the fourth rusher is usually a linebacker, though many teams, such as the Pittsburgh Steelers and Baltimore Ravens, use a talented safety to blitz and confuse the coverage, giving them more defensive options in the same 3–4 look. However, since there are four linebackers and four defensive backs, the fourth potential rusher can come from any of eight defensive positions. This is designed to confuse the quarterback's pre-snap defensive read. Here's an example of a blitz in the 3-4:

End around listed twice and bubble screen has a typo. Fantastic job though, Future.
I finally know what a draw play is. :(

And we were worried about NFL-GAF cluttering up the thread with stupid jokes.

Typo:
"Pancake Bbock" needs to be corrected.
 
Done. Thanks!

Keep pointing any typos you see and I'll correct as I go along. I'll no doubt have more as things go along. Especially the next two sections which are pretty dense material.
 
Thanks for the links, I've never heard of some of those sites before. The Ultimate Guide to NFL Defense definitely looks like something worth digging into.

Thanks for doing this Future, I'm looking forward to seeing where this thread goes (and learning a lot).

Any chance of changing the title to "American Football 101"? The other football (soccer) thread scans in the same word area. Just a request, no big deal if its a hassle, but you may not like us posting drunk "after dark" accidentally in here :)

Should be doable, yeah. I'll send a PM to the mod for that.

EDIT: Updated with 4-3 defense info in the second post.
 
Can we talk rules? I want to know what actual rule the Brady slide tackle last night would be under. I've never seen it before, but I imagine there must have been some rule broken that was left uncalled. You can't do it in baseball or Soccer, so why can you do the high slide in football? Or can you?

My first thought would have been tripping or just a personal foul/unnecessary roughness with danger to the knees or something.

Honestly I don't think they really have a call for that.

It'd be an unnecessary roughness or an unsportsmanlike. It's a non-football action.

I doubt there is anything specific on that, it just seems so odd. Maybe call it a personal foul since the play is technically dead when Brady started the slide and Brady was trying to hurt someone after the fact?
 
What I would really like to know is what the Mike calls when he sees what formation the offense is in and they audible out of it. Is it a variation of the same play, a reassignment of certain players, or a flat out defensive audible every time?

I found this interesting, it was from Peter King:

When quarterbacks go to the line of scrimmage, they most often point to the foe they're using as the middle linebacker, in order for the offensive line to know which man they're going to block. The first man to the right of the "mike'' linebacker, for instance, will be blocked by the right guard, etc. And so when Manning would see Ray Lewis, number 52 on the Ravens, across the line and bark out, "52's the mike,'' Lewis would scurry to the outside of the formation and yell, "I'm the mike!'' And Ed Reed or another defender would slip into Lewis' spot and yell, "I'm the mike!'' They were taunting Manning, and it shook him up.
Says Manning now: "A nightmare. A disaster. They saw me sweating it, and they took advantage of me, to say the least.''

Saw this DK that may shed some light:

http://usafootball.com/news/coaches/lets-talk-football-audibles-defense

He gives some examples of what they would check too but not terribly in depth. Also he states his defensive philosophy clearly from the outset. Other coordinators may end up being far more conservative with what their MIKE checks to.

I like http://www.nepatriotsdraft.com/ , yes it's a Pats based site but they do a good job keeping it readable for non-Pats fans. They do a good job on the assessment of the players and write nice little pieces on a whole lot of them.

Plus they are working on multiple other team focused sites right now.

Great OP, Futurevoid, you went all out.

Just to be clear, we are doing draft talk here, right? Not in terms of what teams have as needs, but with specific players and how they may or may not fit with certain teams and personnel.

Like Tyler Wilson apparently was measured with really small hands today. Does that matter? How did that affect Alex Smith? Dave Kreig was quite the fumbler b/c of his small hands

Not sure if you saw it or if anyone else. But there was one site that had projected NFL success for QBs, it had RG3 ahead of Luck but the interesting part is that it had Russell Wilson ahead of both of them but he was disqualified because of his height. Any ideas what site it was?

Yes. Correct.

Nice start. Maybe throw in some of the more common penalties as well? I know I often get asked what offensive holding is and whatnot from newbies all the time.

Just a few more:

Power Run - A power play is a running play with two lead blockers; the fullback and the backside offensive guard. A typical scheme for a power push is for the linemen to go down on a man in their gap. The fullback will kick out (block) the last man on the line of scrimmage (an outside linebacker or wide defensive end) and the back side guard will pull and lead up either the guard/tackle hole or the tackle/tight end hole and block the remaining linebacker or defensive back. The principle of this play is to out-number the defense at the point of attack. The tailback must read the guard's block and run off that. Teams at all levels will use this as a base running play in their offense. This play is typically run out of I-formations.

http://en.wikipedia.org/wiki/Power_run


Zone Run - Zone running actually has many different variations; an inside zone play or an outside zone play also sometimes wrongly labeled as the stretch (which is in fact a different play). The difference between the three popular zone plays are the aiming point and reads for the ball carrier. While the inside zone has its first landmark around the guards original position, the outside zone aims at the off-tackle area. The stretch usually reads the force defender outside.

Zone Blocking - Zone blocking originates with blocking the first level (defensive line). There are usually two double teams on every zone blocking play (playside and weakside). From each double team, one of the lineman from each will work onto the next level (linebackers). Depending on the flow of the linebackers, either the drive man (inside blocker of double team) or the post man (outside man of the double team) will leave the double team in order to reach the linebacker. If the linebacker reads over the top of the double team (outside) then the post man leaves the double team in order to block the flowing linebacker. If the linebacker comes inside the double team (underneath), the drive/inside double teamer will pick up the backer. This blocking scheme creates cut-back lanes, open pockets of space through which the running back can run. Cut-back lanes are created due to an overcommitment (flow) by the defense and a seal block on the backside by linemen.

http://en.wikipedia.org/wiki/Zone_run

Zone running/blocking has seen a resurgence in the NFL thanks to the success of Shanahan and Kubiak.

And I wanted to clarify "Power Run" from a "Power Run Game" I feel like analysts mislead the audience nowadays.

Good work dude, always been a quality poster.

Whats the best source for NFL Mock drafts? I use Walter football and CBS Sports right now, anything better?

I like Brugler over at CBS, can also follow Matt Waldman, he does stuff for the NYT blog, Football outsiders, has his own site as well. Not sure if Waldman does mocks, but you can shell out $20 and get an insane amount of info on almost every player in the draft, I'm considering it just to see how much work he puts into it.

Honestly, if you have access to ESPN Watch you can go back and watch games yourself, that's what I did the last couple of years, but ESPN dropped my ISP/cable provider from Watch, so I'm shit out of luck. You can get done with a play in 20 minutes, but you're only scratching the surface. At least you get to see the player with your own eyes.

I'm trying to get videos of Dysert/Nassib but torrents may be my only option and it doesn't seem like much of one at this point. There's always youtube, but they don't have much either.
 
I think both NCAA and the NFL had a crackdown on Youtube recently, You used to be able to find a load of videos and breakdowns but now when I search it's mostly Madden clips.

I'm still pissed that NFLN doesn't do better cut ups for the prospects at the combine. Especially after Wellie stalked Steve Sabol to tell him that he'd work for free! They'll cut up their combine workouts, though.

So I'm curious how you guys think the league will adapt to all the new formations and running QBs. My observations with the Rams vs SEA and SF was that they always played zone, but they sat back vs Kap while blitzing Wilson. The other wrinkle was it was 2 deep vs SF, but just one deep vs SEA

It sounds glib, but nearly all of the offensive plays they generated came off physical and mental errors by the Rams terrible FS. I'm wondering how important that's going to be now. If teams have to commit a lot more men to the LoS, how important will safety play be? You need one guy who can hover around the LoS and sort of be a joker or whatever it is called, and another that can cover ground in the back end

In so far as the read option is concerned, you might find this good reading (its more college oriented but it applies). I ran across it a couple of days ago as I putting this thread together and was going to use some of the content in one of the scheme categories. The article is from 2010 but hell I'm honestly learning a ton in the process! Considering the discussion of whether the read option is here to stay or a "fad", I think it will invariably be integrated into NFL offenses moving forward and defenses are going to have to account for it.
