He's a pretty darn good coach in my mind. Won 2 SEC East titles in their first 3 years in the conference. Right? Not bad at all in what is arguably the best conference in football. His timing was good, but victories in the SEC don't just fall in your lap.
Meanwhile Sumlin has gotten most of the attention AJ C's the 2 schools joined... And what has he won? Nothing... Well, except a big contract extension thanks to Johnny M.
