So, you may have blocked this out, but Tom Brady started the Super Bowl against the best team in the NFC, and led his team to a thrilling victory. Let's say that he takes your approach, given that you are a PR master, and he says 2 weeks before the Super Bowl "Guys, I have to come clean, I asked these two guys to doctor our balls after the refs checked them."
You realize... he would have been suspended for the Super Bowl, right? His team would have lost, and you would have thought he was a cheater (with good reason, he admitted to it).
These sorts of things break down by fan bases. If you are a fan of another team,
Tom Brady is already a cheater to you... He was a cheater after the Tuck Rule. He was a cheater after SpyGate. He was a cheater after anything else, and
especially after this fiasco. Yet, if you're a fan of the Patriots, or Brady, or
a fan of the American Dream, then you don't think that Brady is a cheater (back in January). So, back in January, if he says "Hey guys, there's no hard proof of it, but I want to come clean and tell you that l
ike Aaron Rodgers, I've broken the rules by inflating footballs to my preference" then people who aren't fans of the Patriots are going to continue to think he's a cheater, the league would actually have an admission of guilt from him, and then people who give him the benefit of the doubt (Patriots fans) would have to admit this guy isn't completely on the up and up.
Or, you deny, you realize the league has basically no hard evidence on you, you wait 4 months for this 250 page report, you let your team and spokes people point out all of the issues with the report, and then you play it by ear after that. He could still come out this week or next and admit to wrong doing, but I doubt he will. THe court of public opinion decided 13, 14 years ago that Brady is a cheater, and fans of other squads doubled down on it after 2007 (with good reason). So you can either indict yourself
which gets you nothing or you can call the leagues bluff, win a Super Bowl in the process, and wait until May to see what the resolution is.
Expanding on this, think of Ray Lewis after 2000. He could have come out and said, "Guys, I admit it, I was in a club and my gun went off and I was an accessory to first-degree murder. I'm sorry." The court of public opinion determined that Lewis was a murderer, fans of every other team in the NFL knew he was a murderer, Ravens fans gave him the benefit of the doubt, and he let the legal process play out. As it was, there wasn't enough evidence against him, and he went onto have a heralded, multi-SB winning career. And yet, 15 years later, fans of other teams still think that Ray Lewis is a murderer who got away with one. But, he's not in jail, he's a multi-millionare, he's a hall of famer and considered one of the greatest linebackers of all time. Dishonest guy? Probably. Bad PR? Probably not.
