I just don't see the 16 team supper conferences happening...I think the landscape will change regarding expansion of the playoff to 8 prior to that kind of conference shake up; which opens up more slots and then we'll have some stability.
What SHOULD happen is the creation/morphing of the conferences into 8 divisions of 9 teams each, divided into 4 total conferences. But of course that's too symmetric and perfect to work.
SEC would have 2 divisions comprised of 9 teams each. They would play a Championship game and the winner of the Conference would be in the CFP.
BIG TEN would be the same in all respects as the SEC, and their winner would be in the CFP..
ACC would be the same in all respects as the SEC and BIG TEN, and their winner would be in the CFP..
Big 12 would no longer exist, as we know it.
PAC would no longer exist, as we know it.
18 Remaining Members of PAC, Big 12 and other teams would then constitute a new Conference organized the same way in all respects as the SEC and BIG TEN and ACC.
Notre Dame and BYU and Army could play for the CFP Championship if they were a full FB member of these four major conferences. Otherwise they could only play in invitational "bowls".
All the Conferences would be mandated to have all their respective members play all other members of their division on a complete round-robin basis annually. Each member would also be required to play a fully-rotating 2 members of the opposite division.
But again, it's all too perfect.
There would be 72 teams altogether. Four (4) Conferences of 18 teams each, Each Conference comprised of Two Divisions.
The teams could be recognized as NCAA-compliant/semi-pro-amateur.
In Basketball, they could play a perfect double round robin. Or they could play every other Conference team once, and one designated opponent twice.
The "winners" in this new athletic/academic alliance, would be the networks, and all teams except Notre Dame. And the Athletes. "Losers" would be considered to be any of those who were not admitted as one of the 72 teams.
