USC needs UVA to beat VT, Pitt to lose to Cincy, Nebraske to lose to Texas. If all three happen they are in with two wins for sure by my humble calculations.
Florida
Alabama
Texas
Cincy/Pitt winner
TCU
G-Tech/Clemson winner
Oregon/OSU winner
Ohio State
Boise
Penn State
If Nebraska wins, throw out Boise or Penn State. I'd say Penn State.
