I'm not convinced teams won't schedule OOC games of note these days. I think they help, and this season is all we have to go on. Why is UGA ranked 2 and Indiana ranked lower? That's a 2 loss team higher than a 1 loss. For all the complaining by Bama, as I note, their OOC slate was irrelevant, some with Ole Miss.
If those latter two had played another P5 kind of team and won, they might have made it in with 3 losses in conference play. maybe.
