With Ohio State's win over TTUN and Notre Dame losing to Stanford, Ohio State now moves ahead of Notre Dame in all-time winning percentage (72.4666% vs 72.4000%). If you include Boise State, Ohio State would be #3 behind only them and TTUN. However, if you exclude them as many do because they don't have a long enough history, Ohio State would be #2.
Another noteworthy tidbit, if Ohio State beats Wisconsin next week, we'd move into a tie with Texas for #2 in total wins.
