Without players from the south, the Big Ten teams would be hot garbage. The de-regionalization helps them in this case.
And on Saban's comment, if you think about the players when he was coaching and when they were 9-10 years old when their real football knowledge/memories begin, that was pre-2014. OSU was good, but always falling short. And UM was OSU's bitch.
And the rest of the conference was....not great.
If you care to be that specific about it, he's just speaking from his lived experience.
