Yesterday I heard a story about a famous player in football who was a big headache for a losing team. They traded him to a winning team, and he changed overnight into a model player. I can't remember the guy's name right now, but I immediately thought of Cousins. You have to be careful about concluding anything about a player's bad attitude on a losing team. Maybe he's just frustrated he never played for a winner. The guy just wants to win.
Belichick, by the way, has been known to get players like that. Of course, he has an uncanny knack for knowing which players will fit on the Patriots, including draftees.
