There only way there is room for 4 teams from the west is if they went to 16 teams (unlikely) or could go to divisionless with 15 teams (both SDSU and Air Force). The reason I put Boise State and SDSU at the front is because those are the two teams who actually received and accepted invitations. BYU and Air Force have also received invitations in the past, but rejected.
The 14-team divisions would likely include:
WEST
- BYU
- Boise State
- SDSU or Air Force
- SMU
- Houston
- Tulsa
- Tulane or Memphis
EAST
- Temple
- Navy
- Cincinnati
- ECU
- UCF
- USF
- Memphis or Tulane
6 divisional games and 2 cross-overs. So, max one Eastern timezone road game per year.
