I can't wait to see that MAC champion against Alabama. Must see tv!
In this kind of scenario, the top 4 would likely get a Bye. If we go strictly off last year's CFP rankings (1-12 but include the auto bids), this is what a 12 team playoff would look like...
1. Alabama - SEC Champ - BYE
2. Clemson - ACC Champ - BYE
3. Ohio State - BIG Champ - BYE
4. Notre Dame - Highest Ranked At Large - BYE
5. Texas A&M - SEC At Large
vs
12. Oregon - Pac 12 Champ
6. Oklahoma - Big 12 Champ
vs
11. Indiana - BIG At Large
7. Florida - SEC At Large
vs
10. Iowa State - Big 12 At Large
8. Cincinnati - Highest G5 Conference Champ
vs
9. Georgia - SEC At Large
After this first round, they could either reseed so lowest remaining seed plays highest remaining, or it could be a set bracket. In this scenario, 11-0 Coastal Carolina and 10-1 BYU would certainly be upset about 3-2 Oregon getting one of the autobids, but 2020 was crazy with COVID, so maybe it's a bad example as I don't see that scenario happening very often in a normal season.
When you add in the conference championship games as defacto playoff (play in) games, who wouldn't be pumped about a post season like this?
