Yup, basically it went down like this:
-- OSU president, various academics, half of power alums wanted Miles. In fact, when he left the first time, he was told they'd be calling him. (He apparently left OSU because Simmons had basically gone crazy.)
-- Boone Pickens, various power alums wanted Mike Gundy
Result? Plea bargain between the two sides. Miles is HC because of seniority, age and previous OC position at OSU; Gundy gets OC because Boone wanted him in the coaching staff and Miles was told he wouldn't have a choice in the matter there.
He might not have rushed off to follow Saban if it wasn't for Boone. Anyway...
People I know around here that still talk to him say Baton Rouge is waring him out and bugging his family. I just think they might have reached a point to get out of the insanity of the bayou and head to a place with a slower pace but still home to major BCS football. That place is Boulder and he loves it here.
In the end, we don't really know what will motivate a man to make a career change. It's usually money, but sometimes its not, especially when a guy gets older, is established and has some jack in the bank.
