Lot out smoke out there that more expansion is coming with an announcement of Virginia to the B1G as early as tomorrow.
Even a lot of talk that the conference is going to 20. If that happens, I think major college football will be informally broken into a PAC/B1G side (32 teams) and a Big 12/SEC side (likely 32 teams).
If that happens, I see an eight team playoff with four conference champions and two at large teams from each side. Think Ohio State, USC, Oregon, Michigan, Alabama, aTm, Oklahoma, Florida in a playoff.
