How are you going to fit 3 ACC teams into the playoffs? Louisville or UVA would be in automatically. GT would be 12-1, win over UGA, and only loss in a conference championship game.
Based on today's rankings and the above scenario these 10 teams are in:
Louisville/UVA - autobid
GT
USF - autobid
Ohio State
Texas A&M
Bama
Oregon
Indiana
Ole Miss
BYU/Texas Tech - autobid
These teams are/would be bubble teams:
Notre Dame
UGA
Miami
Vanderbilt
Do you think Miami is a lock to get in here? What if Missouri wins out and beats Texas A&M and A&M only has 1 loss? My point is, Miami would not be a lock in this scenario at 11-1, even if it is somewhat wild.
