If Ohio State wins, they have the best resume. That's what counts. Number of quality wins. No bs about style points, close or quality losses. A win is a win and a loss is a loss. If you need to go deeper than that to break a tie, then fine but if one team beats 3-4 ranked opponents with only one loss, that counts for more than anything else.
What exactly gives Ohio State the best resume? If tOSU, TCU and Baylor all win Saturday all thre would only have 2 wins against teams in this week's AP poll:
tOSU: Michigan State(7), Wisconsin (11)
TCU: KSU (9), Oklahoma (18)
Baylor, KSU and Oklahoma
Obviously tOSU and TCU both beat Minnesota currently 27 in the AP. Plus tOSU lost at home to a 6-6 Va Tech team. Don't see how this gives them a better resume.
