Yes, I'll root for him. I think he is suited to be a great offensive coordinator. Head coach and OC at the same time? No. But he really had to go. He didn't adjust, and got stubbor with certain things that he shouldn't have, and also had some influence in bad personnel decisions (Ruvel martin, anyone?).
Good guy, though. Straight shooter in press conferences. Owned his mistakes. I like to root for the good guys.
