Not much. I think the NCAA came a'knocking because he pushed the limits. I don't recall the NCAA handing out any sanctions though.
But people - especially Alabama fans - just loved bringing up how much of a dumpster fire he was at Tennessee.
He is a dumpster fire as a head coach. So was Gene Chizik. So was Shula. However, Chizik was a good coordinator. Shula has done well in his first year as an NFL OC and QB coach at Carolina. Muschamp is another that is right at dumpster fire level as a head coach, but was a good coordinator.
I'm at least willing to give him a chance, because the offense has to change. The same ol' same ol' just isn't getting the job done anymore.
