Starting here in the B1G:
B1G-W
Wisconsin has clinched an outright B1G-W Championship and will play in the B1GCG in Indianapolis.
B1G-E
Ohio State has clinched at least a share of the B1G-E Championship and will play in the B1GCG in Indianapolis.
If the Buckeyes lose to Michigan then either PSU (@UMD) or MSU (@RU) or both would win a share of the B1G-E by winning their final game but Ohio State wins any tie.
ACC:
Clemson has clinched the Atlantic and Miami has clinched the Coastal. They will play in the ACCCG.
P12:
P12-S:
USC has clinched an outright P12-S Championship and will play in the P12CG.
P12-N:
Washington State controls their own destiny. With a win in the Apple Cup they go to the P12CG. Stanford has an OOC game this weekend. The Cardinal have clinched a share of the P12-N Championship and await the UW/WSU result. If the Huskies win the Apple Cup then the Cardinal go to the P12CG.
SEC:
SEC-E:
Georgia has clinched an outright SEC-E Championship and will play in the SECCG.
SEC-W:
The Iron Bowl is for a berth in the SECCG and is probably effectively a National Championship octa-final (term?). Bama has already clinched a share of the SEC-W but if the lose to Auburn they will share the title with the Tigers and Auburn will win the H2H tiebreaker and go to the SECCG.
B12 (I saved this for last because it is the most complicated):
Oklahoma has clinched the #1 seed in the B12CG because the worst they could do is a two-way tie with TCU and they beat TCU.
TCU plays Baylor on Friday. They should win easily (Baylor's only B12 win is over hapless Kansas) and if they do, they will play Oklahoma in the B12CG.
If TCU loses to Baylor on Friday then each of the following teams has an opportunity to tie for the #2 seed in the B12CG:
- 5-3 OkSU (vKansas)
- 5-3 Texas (vTTech)
- 5-3 WVU (@Oklahoma)
- 5-3 ISU (@KSU)
In the event of a tie, TCU will be one of the tied teams and the first tiebreaker is H2H. TCU beat OkSU, Texas, and WVU but lost to ISU. Thus, so long as ISU is NOT involved in the tie, TCU will get the B12CG berth even with a loss to Baylor.
B12 Tiebreaking procedures:
- H2H...2H
- Record against the best team(s), then the next, etc.
- Scoring differential among the tied teams.
- Draw
Thus:
- TCU would win a tie with any combination of OkSU, Texas, or WVU.
- ISU would win a two-way tie with TCU ONLY.
ISU lost to OkSU, Texas, and WVU. Therefore, a three-way tie between TCU, ISU, and any of those three would go to #2, record against the next best team(s). ISU would therefore win a three-way tie with TCU and either OkSU or Texas because they own a win over the #1 team, Oklahoma.
In the event of a three-way tie between TCU, ISU, and WVU:
- H2H2H; tied 1-1 (TCU beat WVU, WVU beat ISU, ISU beat TCU)
- Record against the best team: WVU and ISU would have wins over OU. I think that means that TCU would be eliminated and WVU would go on the basis of their H2H win over ISU.
In the event of a five way tie (TCU upset by Baylor, all of the 5-3 teams win):
First, H2H2H2H2H:
- 3-1 TCU (lost to ISU, beat the others)
- 3-1 OkSU (lost to TCU, beat the others)
- 2-2 Texas (beat ISU and WVU, lost to OkSU and TCU)
- 1-3 WVU (beat ISU, lost to the others)
- 1-3 ISU (beat TCU, lost to the others)
I *THINK* that TCU and OkSU would then revert to the two-team tiebreaker and TCU would go to the B12CG on the basis of their H2H win over OkSU.
