Here's a scenario:
#1 - Oklahoma
#2 - Michigan State
#3 - North Carolina
#4 - Ohio State
Now hear me out cause I don't see this happening, just throwing out a "worst case" scenario. Florida beats Bama (won't happen, but could) and no way the committee takes a 2 loss team. Although, I could still see them taking Florida due to the SEC bias that clearly exists. The Tar Heels beat Clemson and all of a sudden, you have a host of quality one loss teams to choose from. No one travels like Ohio State and with their only loss being to the Big10 champ, they look better than Clemson.
That said, here's what I see happening...
#1 - Clemson
#2 - Bama
#3 - Michigan State
#4 - Oklahoma
