This is not complicated. The big time coach worthy of getting an elite pay check is probably doing just fine...he can pick and choose his situation. Take John Gruden. He's already making what Butch Jones was making doing a part time job without any of the hassle that goes along with coaching college football. He would have to want to leave ESPN. "Backing the Brinks truck" doesn't matter nearly as much as trading in a cushy, comfortable gig for the unknown of being a college football coach.
Take Jimbo Fisher. He had a bad year. Maybe he wants to reset his clock somewhere else. He can pretty much take any job he wants. Everyone involved will pay him what he wants. He has to decide if he wants to leave FSU, or just work the schools over to get a raise at his current job. If he decides to leave, what's a better job, what's the best fit for him, his family and his assistants and their families. Would I blame him for taking, say the TAMU job over the Tennessee job? Not one bit.
The key is, they have to want to leave their current positions, money alone cannot make them.
This whole notion that a boatload of money is all it takes is juvenile.
