I heard Saban and Kiffin don't exactly have a lot of love lost for each other.
Kiffin endorsed Deion for the Auburn job. I've never seen a coach do that before then turn around and go to that school. I think he's happy at Ole Miss.
I think Nebraska would definitely be on the radar. If they offer him $10M a year with an 8 year guarantee, they are going to listen and they are going to tell Ole Miss and any other interested parties what the deal is and where they need to be.
Now, would Kiffin actually go to Nebraska? I would think not unless it really was a godfather offer. I'm just not sure Nebraska is willing to step out there with a Jimbo type offer (which is what I think it would take), especially seeing how that's working for A&M.
