2) Ohio State
First two out:
I think Alabama could drop out after conference championships depending if teams like Minnesota or Oregon win their Conference. I believe Alabama doesn't have a single win against a top 25 team. Oregon is also missing wins against top 25.
Although its hard to have a win against a top 25 since when you beat a top 25 team they often drop out of the top 25.
I think Clemson has to win out to be in. Minnesota and Oregon have to win out to have a chance. LSU I feel could lose a game and still get in with all of their great wins. And Ohio State has 2 top 25 wins and could add Penn State, Michigan, and Minnesota so could have 5 top 25 wins. Its possible they could lose a game and get in also.
Georgia has a bad loss which can be a death sentence.
