Honestly, I'm kinda surprised that the league hasn't dismissed the suspension on its own. It now has the second circuit on record as saying that Goodell can do whatever he wants, whenever he wants, up to and including breaking labor law, and they won't do anything about it. They've also established a process by which they can ensure that any future arbitration disagreement end up being argued in the second circuit.
Seems like enough of a win that they should eliminate any incentive for Brady to continue the fight, purely on the slim chance that he gets an en banc appeal or makes it to the SCOTUS and wins.
If I was commissioner, I would drop Brady's suspension yesterday, and make a statement to the effect of "while I am pleased that the second circuit has affirmed my authority as both commissioner and arbitrator in all cases relating to the integrity of the game, I also wish to extend a hand in cooperation to the players' association and the Patriots organization. While I stand by the Wells Report, I have decided to reduce Tom Brady's punishment to the maximum fine allowable under the collective bargaining agreement". Then again, if I was the commissioner none of this nonsense would have happened in the first place, because this was a ridiculous case and a witch hunt from day one.
