saban and Kirby weren't masterminds they just understand its about talent.Butch Davis was arguably out coached in every game. His OC was Larry Coker.
But he simply put so much talent on the field that the coaching issue alone did not stop UM from winning big.
Your statement about what a head coach needs to be is being made today in Tuscaloosa, Athens, Ann Arbor, even Columbus.
Every team is flawed. Every coach has limitations. We will never find a perfect coach because outside of arguably Nick Saban and his ridiculous budget, that coach does not exist.
also, I don't want to hear from people this is the best offense Mario will ever field. This offense has how many nfl players starting right now? or even in the two deep?
