yeah, and mighty Chip Kelly finished his NFL stint at 2-14 and folks were beating down his door to come back to college. I seem to remember Nick Saban tearing it up in the NFL also. Past NFL performance is not a good indicator of college success.
No, the 'why' comes from no way in hell anyone knows if he can do the job or not...I'd rather send a stud linebacker son to play for Herm Edwards than Todd Graham any day of the week.. How bout you?
