I would think Clemson and FSU would be close but it’s a narrow window. Bundling that protects high profile rivalries and makes the scheduling more manageable help boost the value of some schools.
There is an argument that 4 power conferences of 16 teams makes the most sense but I think that ship has sailed because the PAC and Big 12 have been neutered.
So the big question is how big can the SEC and B1G get without watering down the brands and making scheduling still manageable? I think that number is going to either 20 with 5 team pods or 24 with 4 team pods. If you go with 5 team pods and 10 conference games you play the teams out of your pod once every 3 years. 24 teams it gets a lot more complicated.
I could outline the math in more detail but it would be boring. Honestly I think these conferences max at 20 or you run the risk of it being 5 to 6 years between playing some people in your conference.
I guess you could grow them to 40 teams, 10 team divisions, never play the teams in the other divisions and do a playoff conference championship. I don’t see anyone wanting that so we are probably looking at 40 to 48 teams total in the two super conferences Combined.
