Maybe, but….True. But even several of the schools in the Big 12 and ACC will not be getting the payday that they are now. The entire things is going to be shaken up eventually.
CFB is never going to make an effort toward parity like the NFL claims to. There’s zero real interest in that, it’s more about making sure that the teams who have big markets stay popular and keep those markets. There’s also interest in having big matchups between those teams. But, to keep those matchups interesting and relevant, they have to pad the schedules.
There’s far less interest in watching a 6-4 Michigan play a 5-5 Alabama. They want those matchups to be between teams with less than 2 losses so they can bill them as having playoff and championship implications. To do that, they have to make sure that their schedules are filled with winnable games.
Sure, they could have Michigan State play Texas, Alabama, USC, Ohio state, Penn State, etc., and load up on “marquee” games. But that’s going to lead to losses and knock teams down. They’ve got to limit those games and make sure Michigan plays Illinois and Purdue and pads their record. To do that, the Big 10 will need to keep a couple teams around to serve as the whipping boys. Same with the SEC.
There may end up being some dropping teams and shuffling around, but they can’t drop all the weaklings. Every top tier team, in order to remain top tier, has to have teams to beat.
