Worst of all would be Georgia losses to GT, but they still get in and win the SEC as a guaranteed team with 3 losses, then GT loses to Miami in ACC champ
SEC(4): 10-3 Georgia, 11-2 Alabama, and 2 other 10-2 teams
ACC(2): 12-1 GT, 12-1 Miami
B1G(3): OHSt, Oregon, Indiana
B12(1): whoever...
other champ (1): whoever...
so one open at large for ND which could easily be placed behind a 5th (10-2) SEC team or an additional 11-1 B1G/B12 team.
Fortunately, the scenarios of 5 10-2 or better (which includes a 10-3 champ) SEC teams will probably become rarer this weekend when BIG GAME KELLY falls to TAM, and/or the Hyde version of Arch Manning shows up again against MSST, or Tennesse has another of its prototypical flops against a lesser road opponent in Kentucky
