has not made their final judgement yet on Notre Dame vs Oklahoma. If/when they do, I think a 11-1 Notre Dame would come in ahead of an 11-1 Oklahoma.
The one common opponent was Texas. Oklahoma lost by 7. Notre Dame beat them 38-3. Notre Dame appears to have played a tougher schedule. Notre Dame's one 2-point loss was to #1 Clemson on the road. It's the best loss in the land. Combine that with wins over Stanford, Temple, Pitt, Navy & USC. Notre Dames wins are also better than Oklahoma's.
