I think just the names alone would be a big difference in recruiting.
Les Miles - Well known name in FBS college football who was successful at a big time football college....LSU
Chris Klieman - Successful FCS college football coach, multiple championships, ect….
Now don't het me wrong Klieman is a great coach and any FCS football program would be glad to have him but lets not forget that the only reason he got offered the job is 1) Gene Taylor and 2) Every other applicant who was more qualified turned it down. Not saying Klieman wont be successful at the next level because no one can say that. We will find out soon enough. Best of luck to him!
