Texas best chance is if it goes chalk, less Louisville beating Fla. St.....I think Bama, UGa, and a very outside chance that Ohio St. could get in over them all with the 1 loss scenario.
I believe Ga. is in no matter what. If bama wins, they are in w/ Georgia, Wash., and Michigan.
Ohio St. needs Fla. St. And Texas to lose, but I suppose there is some scenario where Ohio St. gets in over Texas even if they win, but I doubt it. Not enough wins over ranked teams and the B1G is a joke this year. In the scenario where Bama beats UGa, Michigan is 1, Wash 2.....that could bolster Ohio St. to the last spot over either Bama, Georgia, or Texas. IMO the committee has the toughest decision in the scenario where Bama wins, and Texas win but by narrow margin.
If bedlam happens with Bama, Iowa, Okl. St., and Louisville winning, then we get Bama, UGa, Wash, and Ohio St.
