I think that it's absolutely ludicrous that Saban is even being mentioned as a possibility as a head coach. Even if he wasn't coaching the Dolphins right now, I'd still find it hard to believe that he'd leave "retirement" in order to coach at Alabama, especially after when he left LSU. In fact, I'm sure that he would still be at LSU right now if he hadn't left for the NFL. Also, if somehow some way Saban coaches at Alabama, he'll most likely leave after 3 years, unless he finds total happiness coaching at Alabama, much like how Pete Carroll has enjoying coaching at USC or Mack Brown coaching at Texas.
I'm not saying that he's a bad coach, but I want to see REALISTIC coaching candidates, not some random coach that was awesome in college and is coaching in the NFL right now. Furthermore, I don't think that Shula will leave this offseason. He will be given one more season to prove himself with the recruits that he has. If things are sub-par or fall apart after 2007, then I think he will either resign or be fired.
My coaching candidates (assuming Shula gets fired after 2007)? Pat Hill, coach at Fresno State; Steve Sarkisian, Lane Kiffin or Nick Holt at USC; maybe Bobby Petrino of Louisville; or Gene Chizik of Texas. I think all of those coaches would consider Alabama as an attractive coaching opportunity now that we're no longer on probationary status.
