The best way into the playoff will be as conf champ, and there will be little desire to schedule non conf games that are difficult.
Also, it might isolate the conferences from each other as well for the same reason.
Depending on how they expand it matters too. If they simply guarantee the best non Power 5 a spot in the field of 8, that just leaves 2 spots left for ND, and most conferences will still have a one loss non champion given the cupcake scheduling....in which case, ND will still be on dicey ground with one loss.
