Notre Dame

New Mexico St

Idaho
Boise St
@Oregon St
@UCLA

Illinois
@Michigan
Maryland
@Wisconsin
Washington

Hard to imagine the CFP committee not giving the hosting nod to an at large candidate from the B1G/SEC with 1, 2 or maybe even 3 losses from the above schedules over a 1 loss Big12/ACC school. Not saying I would agree, just that I would be surprised if it weren't that way.
