Lane Kiffin will always regret it if he quits on his Ole Miss team.
He'll always have remorse if he decides to go take another job -- Florida or LSU -- right on the verge of leading a likely 11-1 Rebels team into the College Football Playoff. He'll never live down the fact he turned his back on a locker room ready to fight with him for a national title -- all for the perceived greener grass of Gainesville or Baton Rouge.
What kind of coach would do that?
This has nothing to do with what job offers more advantages or money or proximity to talent.
