I have had this conversation with fans both on and off this board. Most (including me) believe Kiffin will be here 4-5 years max.
One of two things will happen.
1. Kiffin wins, and the NFL comes calling (this is what I think will happen).
2. Kiffin loses, and he's out.
Kiffin is an 'outsider'. He will not receive the same leeway with won/loss as Majors or Fulmer received. That's just the cold hard facts.
