If Clemson and Bama keep winning, they are in the playoffs.
If ND hadles Stanford and wins decisively, they could take the 3rd spot.
Whoever wins the Big 10, and wins big, could vault Okla for the 4th spot.
This would tell the Big 12 they are being punished again for not having a championship game for the 2nd straight year. That could be enough to force the Big 12 to expand.
