While ND is playing a 12 game schedule it will compete against other teams playing a 13 game schedule. Without a Conference Championship game in it's schedule ND will have to be undefeated......12 and 0 and beat all opponents soundly. And even then that may not be enough. A number of variables will come into play:
- There could always be 4 other undefeated teams that are 13 and 0.
- The voting committee might feel like they "owe one" to the likes of TCU or other similar cases.
- The whole strength of schedule might come into play and if ND's opponents are having a bad year that would diminish their claim for a playoff spot.
- I believe most CFB fans acknowledge there is a bias towards the conferences. Sure, and why not. Look at who's voting. Consequently, even a one loss team like Oregon last year might overtake an undefeated ND in the voting.
