I understand the concern and the somewhat poor position that KSU is in. However for the scenario that KU goes to big 10, Texas / OU to the PAC or SEC and the B12 folds to play out there has to be a number of things lineup before the GOR runs out in 2024-25.
1) Texas and OU have to be able to make more money than their current B12 pay from Tier 1 & 2 as well as their own Tier 3 networks. For OU the SEC could probably make that happen. For Texas, and the LHN, the current SEC and P12 Networks would need to up their pay to make it work. I don't see how the PAC12 could offer them more money... I could be wrong.
2) Texas politics would have to allow the change... we have seen this before with Richards and Baylor, the blowup over TAM/ Texas split, the pending B12 and Texas split and recently the B12 and Houston. For Texas to leave Tech, Baylor and TCU out in the cold it will take some massive political work.
3) If I remember correctly, Kansas and Oklahoma both have one board of educators to govern their schools. Therefore, for KU and OU to split off and leave KSU and OSU the boards would have to approve that... not to mention potential political action. That seems like a big step. Missouri and Nebraska did not have this say problem because they are the only FBS football schools in the state.
4) This is minor, but I think the move to a Power Four is somewhat contingent on the four team playoff (in football) format. Between now and 2024, this could change - especially with the all SEC finals. Obviously TV dollars are going to dictate a lot of everything, but we'll see what happens.
5) Finally, as the article posted above points out I think we are finding that eyeballs in a state, television viewership and success of a network aren't allows correlated. Did adding Rutgers do much for the B10? What about the PAC12 network, they have tons of eyeballs but millions more cord-cutters and some very empty football stadiums. I have no idea what streaming will do, but again there are a lot of balls in the air here.
As always, KSU can only worry about what they can control: keep winning, keep building facilities, keep building the brand, keep filling stadiums, etc. Demographics will be hard to overcome, but KSU can do a lot to help itself in the next several years.
