That's one of the real unknowns about O. Can he hire and retain top assistants and does he know when it's time to send someone packing? If O ends up being the guy, I think Ensminger remains OC. I'm not 100% sold on that either. I'm pulling for Ed, but he still has much to prove IMO.
If Holgorsen gets anything close to serious consideration, the LSU coaching search is in full fledged panic mode!
The relationship between O and Kiffen was discussed on Finebaum today, it was said that Kiffen to LSU as OC could happen with the right persuasion from O.
Kiffen knows the way to a top HC job is winning championships as a coordinator. I don't think he leaves bummer unless it's for a HC job or Saban gets tired of him. Sark would be the more likely candidate if O brings in someone new.
