The following list describes my decision making process:
1. Alabama: As a Vol fan I really don't need to elaborate on why I don't want them to win.
2. Clemson: I don't really have a problem with Clemson. However, the Vols recruit against them, so it would be better if Clemson didn't win the title.
3. Oklahoma: I don't like Bob Stoops (or Eric Striker), so I find it hard to root for Oklahoma. However, given an OU vs. Bama scenario, I would pull for OU.
4. Michigan State: Like Clemson, I don't really have anything against them. I'm not a Big10 fan, but I could accept Michigan St. winning the championship (definitely better than OSU winning).
I think Alabama will likely beat MSU. Alabama is built to stop the type of offense that MSU runs.
As for Oklahoma and Clemson, I really don't know who will win this one. I'm inclined to believe that OU will win in a relatively high scoring game.
