I could see a 1 loss-ND not making it if the 1-loss P5 Champs are one of Ohio State, Clemson, or Alabama/Georgia/LSU/TAMU/Florida. Or USC (or any other 1-loss P5 champ) that beats ND that year. In fact, I see several ways they wouldn't make it. My argument is against those who say ND has to be undefeated to make playoffs because they don't play a conference championship.
