Not a major difference, but Cignetti is actually 63. I think that 8-10 years is a good stretch in today's world of college football, and he could likely manage that somewhere .... if he chose to leave IU.
The man is very intriguing. His father was a longtime cfb head coach, including at WVU, where he gave Nick Saban his first job. His brother is an assistant at Pitt. Curt Cignetti served as an assistant at several P4 schools before spending 4-5 years at Alabama under Saban in the latter half of the 2000's.
Subsequently, he has been a head coach at a couple of lower division schools, immediately turning around the programs and taking them to the playoffs. He built James Madison into a relative power, replicating the same success in his first year. He is only in year one in Bloomington, but everyone can see the immediate impact he had.
Two other things: He can recruit (was recruiting coordinator at 'Bama) and the man has more fire and energy than most coaches of any age.
Not everyone is enamored with him, but I would like for UF to take a look at him if/when we let Napier go.
