Exactly. Beating Texas, OU got redemption for their only loss. tOSU beating Michigan again would not have helped them as much as a convincing rematch win over Purdue. If Michigan wins a rematch with tOSU, it doesn't erase their 23 point loss to tOSU. I think Georgia stays ahead of both tOSU and UM regardless of who wins the rematch.
Delaney needs to realize that Clemson played a 7-5 Pittsburg team in their CC game, but still became the #2 seed.
Obviously it is better for NU if the Divisions remain as they are and the CC game remains a contest between the 2 division winners. NU will always have a decent chance to win the West and get to a CC game, but always precarious a chance to get in a CC game if divisions disappear it becomes subjective.
I don't think the B1G ADs would support Delany's idea.
