Agreed. Which is why most of this is basically just thinking out loud.
Yep, we are just speculating.
So lets narrow it down, look at 2022 when your Boilermakers were in. Heading into the CGs the rankings were:
- 12-0 UGA vs #11 SECCG
- 12-0 M vs nr PU, B1GCG
- 12-0 TCU vs #13 KSU, B12CG
- 11-1 USC vs #12 Utah, P12CG
- 11-1 tOSU idle
- 10-2 Bama idle
- 10-2 Tennessee idle
- 10-2 PSU idle
- 10-2 Washington idle
- 10-2 Clemson vs #24 UNC, ACCCG
- 9-3 LSU vs #1 UGA, SECCG
- 9-3 Utah vs #2 USC, P12CG
- 9-3 KSU vs #3 TCU, B12CG
- 9-3 FSU idle
- 9-3 Oregon idle
- 9-3 OrSU idle
- 9-3 UCLA idle
- 10-2 Tulane vs #22 UCF, AACCG
If this had been in the 12-team era:
- SECCG: UGA is in either way, gets a bye with a win. LSU is in with a win, probably out with a loss.
- B1GCG: Michigan is in either way but gets a bye with a win. Purdue is in with a win, out with a loss.
- B12CG: TCU is in either way, gets a bye with a win. KSU is in with a win, out with a loss.
- P12CG: USC is in either way, gets a bye with a win. Utah is in with a win, out with a loss.
- ACCCG: Clemson is in with a win and would get a bye if USC, TCU, or Michigan lose. With a loss they'd be sweating out the selection. UNC is in with a win, out with a loss.
My best guess is that the top-10 are all more-or-less locks except that if there are a bunch of upsets then they can't all go.
In the actual event:
UGA, M, KSU, Utah, and Clemson won the SEC, B1G, B12, P12, and ACC CG's. Utah's win gets them in so the 12-team CFP would have been (based on CFP rankings):
- #1 UGA, SEC Champ
- #2 M, B1G Champ
- #7 Clemson, ACC Champ
- #8 Utah, P12 Champ
- #3 TCU
- #4 tOSU
- #5 Bama
- #6 Tennessee
- #9 KSU, B12 Champ
- #10 USC
- #11 Penn State
- #16 Tulane
Teams left out:
- #12 Washington
- #13 FSU
- #14 OrSU
- #15 Oregon
Washington gets knocked out because of TCU's and USC's upset losses to KSU and Utah. Further upsets by LSU, PU, and/or UNC would knock out (sequentially):
- #11 PSU
- #10 USC (maybe, they tend to not knock teams for playing extra games)
- Tennessee
- Bama
My thinking is that the B1GCG as #2 M vs nr PU is interesting to:
- Fans of the participants obviously
- Fans of Clemson, USC, Utah, TCU, and KSU because their shot at a bye improves with a PU win.
- Fans of Washington, PSU, Tennessee, Bama because they chances at the CFP improve with a M win.
In a division-less format the B1GCG as #2 M vs #5 tOSU the B1GCG is interesting to:
- Fans of the participants obviously.
- Who else? I just don't think it matters to anyone else because from an outsider perspective one of them is getting a bye and the other is getting in. The only difference that I can see is that if tOSU wins, tOSU gets a bye and M hosts where if M wins, they get a bye and tOSU probably travels.
