Petrino's history of frequent job hopping would mark him off my list. They would be better off hiring an experienced Offensive or Defensive coordinator from a regular top 10 team like U of L did. The difficult part of being a head coach is being able to recruit the best set of players and assistant coaches. If they're really good, the assistants and players shouldn't need much from the head coach during a game. They still have to yell for the fans watching on TV though.
