i guess we could go through and say 'this year it's 5, this year it's 2, this year it's 9' etc. but that won't ever happen and would be a logistics nightmare.
I think it was
@ELA who first said years ago that the ideal would be a flexible playoff where we include the number of teams needed. Looking at past years:
2022: Georgia and Michigan were undefeated league champions. No need to include Ohio State (lost to M) nor TCU (didn't win their league) so just have UGA and M play in a NCG.
2021: Bama and Michigan were 1-loss league champions. No need to include UGA (lost to Bama in SECCG) nor Cincy (laughable SoS) so just have Bama and M play in a NCG.
2019 (skipped 2020 due to pandemic altered season): LSU, tOSU, and Clemson were undefeated league champs but you need a fourth to balance the schedule so do what we did with LSU v OU, tOSU v Clemson.
2018: Bama and Clemson were undefeated league champs so they are obviously in. Notre Dame was 12-0 so you pretty much have to give them a shot. Oklahoma and Ohio State were both 1-loss league champions so one (or both) of them would be next. The sixth and seventh strongest arguments belonged to UGA (lost SECCG to Bama) and UCF (12-0 but laughable SoS). The eighth would be either 10-2 Michigan or 10-3 P12 Champ Washington depending on how heavily you weight league titles. If it were up to me I'd do a six-team field with ND/UCF and OU/tOSU playing for spots against Bama and Clemson. That excludes UGA and Michigan but they both had two losses and didn't win their respective leagues and it forces undefeated ND to play in the first round but tough luck, you didn't win a league title game like Bama and Clemson did.
2017: Clemson, Oklahoma, and Georgia were all 12-1 league champions so they are obviously in. After that it gets tricky. The other two league champs were 11-2 tOSU (lost to OU and Iowa) and 11-2 USC (lost to WSU and ND). Also in consideration would be a 12-1 Wisconsin team whose only loss was in the B1GCG and an 11-1 Bama team. Auburn was a really odd duck that year. They had wins over both Bama and Georgia and both were big wins (12 and 13 points) but they also had three losses to Clemson, LSU, and UGA. I'd go with an eight-team field of:
- 12-1 Clemson, ACC Champion
- 12-1 Oklahoma, B12 Champion
- 12-1 Georgia, SEC Champion
- 11-2 Ohio State, B1G Champion
- 11-2 USC, P12 Champion
- 11-1 Bama
- 12-1 Wisconsin
- 10-3 Auburn
Fun match-ups:
- Clemson vs Auburn is a rematch of an early season game that Clemson won 14-6.
- Oklahoma vs Wisconsin is great to see Oklahoma playing a playoff game not against an SEC team.
- Georgia vs Bama is actually NOT a rematch because Bama missed the SECCG due to their loss to Auburn.
- Ohio State vs USC is a traditional Rose Bowl matchup.
Then in the next round:
- Clemson/Auburn vs tOSU/USC
- Oklahoma/Wisconsin vs UGA/Bama
2016: Bama was an undefeated league champion so you could just give them the title and call it a day. If we have to have at least one postseason game then I'd take a three-team field of Bama (bye), Clemson, and Washington as those two were the only two 12-1 league champions.
2015: Clemson was an undefeated league champion so you could just give them the title and call it a day. If we have to have at least one postseason game then I'd take a three-team field of Clemson (bye), Bama, and MSU but that excludes 11-1 Oklahoma.
2014: Florida State was an undefeated league champion so you could just give them the title and call it a day. The problem is that FSU looked shaky all year even in a pretty weak ACC. Bama, Oregon, and Ohio State were all 12-1 league champions while Baylor and TCU were 11-1 co-champions of the B12. I'd go with a six team field giving byes to FSU (undefeated) and Bama (highest ranked of the 1-loss teams). Thus, Oregon/TCU and Baylor/tOSU would play for spots against FSU and Bama.
This is a fun thought experiment and it is theoretically ideal but you are right, the logistics would be a nightmare and it would never actually be adopted.
