My vote says it is USC. I know Oregon State 'could' beat them, but I doubt it will happen. I would have said UCLA could do it, but after watching Cal-USC, I doubt that as well.
Here is something that makes my day, though: The Vols can affect who makes the Orange Bowl. If we can beat Auburn in the SEC championship, I believe Oklahoma will go. If the Vols lose, I think it will be Auburn.
My prediction for the rest of the season:
Vols win the SECCG, Oklahoma vs. USC for the Orange Bowl, USC wins.
or
Vols lose the SECCG, Auburn vs. USC for the Orange Bowl, Auburn wins.
