I wouldn't be surprised to see the Big 10 go to 24 teams, and have the Great Lakes conference and the Atlantic Coast Conference. It will be just like the NFL, with a multi round playoff.
I suspect that as a conference that is still an academic conference that Delaney is not amused by the lack of academics going on in SEC Athletics. Which is why I think you are going to see winning a B1G Championship become harder and more significant. Also - I think that as the tea leaves fall, Notre Dame will be forced to join.
I also think you are going to see the non conference games go down to 1 game for protected rivalries such as Iowa State.
