Granted... its a bit far-fetched. But it's just as likely as 3 SEC Teams in the Playoffs, so why not?

1) LSU Wins Out including beating Bama and the UT-UGA winner
2) Clemson wins out
3) TCU wins out
4) tOSU-Michigan winner wins out and the other team only has that loss
5) USC-UCLA winner wins out including beating 11-1 Oregon

13-0 B1G Champ tOSU or Michigan is in
13-0 ACC Champ Clemson is in
13-0 Big 12 Champ TCU is in

Teams available for the 4th slot:
1) 12-1 Pac XII Champ USC or UCLA
2) 11-1 tOSU-Michigan game loser
3) 11-2 SEC Champ LSU (who lost to FSU and TN)
4) 12-1 SEC Runner-Up Tennessee or Georgia (who lost to LSU in Championship)
5) 11-1 Tennessee-Georgia Game Loser

It's quite possible that the Pac XII Champ would be the 4th Team. If not, then the tOSU-Michigan loser still might be ahead of the 3 SEC teams.

That scenario is NOT going to happen, but it sure would be fun!
Go Tigers! And go Tiguhs (just for chaos)!
