Iowa? To the national championship? Michigan would be their first victory against a currently ranked team...and Iowa has TWO losses... and to Wisconsin and Purdue? Notre Dame beat both of those teams. The SEC will get a berth. Unless Houston beats them, Cinci will get a berth. And then there’s Notre Dame, and the winner of the Oklahoma-Oklahoma State game.
If the winners in DEC are:
GA
IOWA
BAYLOR
then GA is #1 and
IOWA, BAYLOR, ND, AL, OREGON are alive for the other 3 spots.
(ND hasn’t beaten a top-25 team. WISC dropped out today)
