Yeah, we'd all hate to have a coach who wins every big regular season game against teams not named Auburn, and still wins most of the rest of them too. BK is Muffet but Saban is Geno.
If Saban ever considered ND it would be his own desire for a "unifying project" (like Nietzsche's
ubermensch). Otherwise, he would probably avoid ND for the same reasons Urban did. I certainly don't think ND should change its standards for a coach.
Anyway, playing Saban tough will be enough for me. It will help recruiting a ton, too. 2017 is a top 5 class now and getting into the playoff will help it finish as one.
