You say a "bit" of an attitude. I don't remember if he wouldn't come out of the game or he wouldn't go back in the game this past season, but any player that feels he can undermine the authority of the coaching staff, has no place on the team. It is irrelevent that the coaches he was feuding with are no longer with the team. If he did it before, he'll do it again.
PS As far as him wanting to play here in Buffalo, take off the blinders. Players will go wherever the most money is....period.
