Okay hear me out. I love a good conspiracy theory. I have my tinfoil hat on. It's a little crooked, but that's okay. It works, It still works
The B1G has added all of the heavy weights to their conference. USC, UCLA, Oregon, Washington, Michigan, Ohio State, Penn State, Nebraska, Wisconsin.... They cover the map from the Midwest to the West Coast and back to the East Coast. The B1G is fine now. They got them all. Other than adding Notre Dame, it's just a wait and see type of game.
The SEC has added OU and Texas for 2024. Which is pretty darn awesome for the conference. But I still think they know they are behind the B1G a little bit now, and might want to reach out to Clemson and someone else from the Southeast (could be Miami, FSU, Louisville, or North Carolina perhaps.....???)
As we move forward and really look into the future, things are going to change a lot. The college football landscape is now P4 and G6 (previously P5 and G5). The playoffs have expanded it's format with more teams for the tournament.
The Big 12 (gotta Love them!) has been doing all they can to add competitive schools to the conference. Football/Basketball/Baseball. Cincinnati, BYU, Houston, Central Florida, Colorado). They doing all they can since Texas and Oklahoma told them to f#&% off and head for the SEC. So I really appreciate the Big 12 holding it together and keeping it balance.
And still, they feel like a group of G5 misfits

Nothing wrong with that! Because right now, they are in better shape than whatever the Pac 12 is doing (as they implode) and to be honest, as long as the ACC remains the same - a few heavy weights at times, but that's it - I think the Big 12 is just as good of a conference. Which isn't saying much for the ACC. And the Pac 12 is technically out as a P5 conference (No USC, UCLA, Oregon, Washington).
So to me I think we are seriously moving towards a P2 (Big & SEC) and G6/8 format. When the playoffs come, traditionally 4 teams from the P2 Big, and 4 teams from the P2 SEC, with 4 teams coming from the new G6/8. And occasionally it will be unbalanced (3 from Big, 5 from SEC or vice versa)...... but at the end of the day, nobody will be too concerned because 8 of the best 12 teams will be in the playoffs. And we all know the TV money will be all for it. The only difference is that the landscape of college football will be a little different from what it was in the past (60's/70's/80's/90's/2000's). But still putting out the same great college football product - especially late in the year and into the playoffs.
