Everyone who is saying bring in Pettine as DC doesn't understand either man. Rex is far too much of an egomaniac to let someone else run the defense, and Pettine is not about to become a puppet with Rex's arm up his ass far enough to make him speak.
Also, Rex keeping his mouth shut? Really?
I can't think of a realistic offseason move that would get me excited for next season. If Rex can manage to keep his head out of his ass, and the team manages to get and stay healthy, the team should be better overall. But then again the schedule is harder next season. At this point I expect another mediocre season, and if the stars align right the Bills could back into the playoffs. But excited, hardly.
