You never EVER lay all your cards out on the table when you plan on fighting someone in court. Doing so gives your opposition the advantage. By waiting until Brady has received whatever punishment the league decides to dole out for doing nothing, then Brady can file his appeal with the court in Minnesota that hears all the cases involving players and the NFL. Once you are in court, and only then, is when you blast away with all guns blazing to shred the NFL and it's ridiculous BS.
Furthermore, how many times do you have to be told that the SCIENCE included in the Wells report actually SUPPORTS the idea that the Patriots didn't tamper with the footballs. It was only the conclusions by Wells and Exponent that are flawed. Also, there have already been numerous people who came out and showed that just the difference in temperature could result in the changes to the footballs. There were at least 2 different well known professors and a well know company that provided the information.
Rest assured, this will be done long before the end of training camp and the league will be much sorrier for it.
