And this doesn’t even have Notre Fame taking on if the at large bids.

Don’t count on the 3rd undefeated B12 team that is left out of the conference championship game to be an at-large bid.

If two of unbeatens meet in the B12 championship, maybe the second place team gets an at large. Or if they get blown out, maybe the 3rd place still-unbeaten team gets and an large. I doubt they give B12 three at-large bids when they are trying hard to only give us 1 bid.
