Short tenure you just described Saben's head coaching career.
I know Saban from his 5 years at LSU. I think he was at Michigan State for 6 years (I might be wrong about that by a year). He was with the Dolphins for only 2 years but you just don't have the control in the pros as HC that Nick desires.
Bottom line is that if I had to choose a coach for my college FB program it would be Nick Saban above anyone else. He is a winner. He does it the right way...he recruits decent kids that are quality players, he boots kids if they don't do right, he demands they work towards their degree, and he wins championships with his coaching.
