My opinions on how it should go, not that it will go this way.
Notre Dame is in because they are done and undefeated.
Winner of Alabama / Georgia gets in. Loser stays home unless a lot of other contenders also lose. If you can’t win your division you shouldn’t be in period barring extreme circumstances.
If Clemson wins next week they are in. If they lose they are out by not winning their division.
If UCF wins next week they are in. I don’t want to hear about lesser division and the SEC is soooo hard. Mid majors have proven in past years they were deserving. For instance when Boise State went undefeated and beat the Adrian Peterson led Oklahoma Sooners in the Fiesta Bowl. Oklahoma should have been playing in the title game but lost a game due to a horrific ref call near the end of a game that literally did cost them the game and replay was 100% the wrong call. So if Boise can beat one of the teams that should have been in the championship why not the ones that actually did get to play there. Ditto with UCF. Either all teams get a fair shot or the system is invalid.
Ohio State gets in before Oklahoma if a loss by someone else sets up a spot for one of them. Ohio State has a better signature win coming this weekend against Michigan.
