Mixed feelings on the guy. Sometimes he did a great job, sometimes he was a bonehead. I would compare his stay in Madison with that of Les Miles in LSU - the coach everyone loves to hate, but usually gets the job done. I could see him being a success in the SEC, but we shall see. It will depend upon his coaches

I'm not sure why he left - there were rumors of internal friction and that his contract was not going to be honored after this season. Also, I think he got tired of living in Alvarez's shadow.
