Tom Brady obstructed justice, went outside the league to get a court order striking down his suspension, and the league let him play anyway. They could have just paid him to stay out of the stadium for those four games, but they compromised the integrity of the game by letting him flout his suspension.
I hope Roger Goodell immediately vacates any Super Bowl win if the Patriots win. Show some freaking spine and enforce your own rules, if not on the player, then on the team who employs him. Of course he won't.
