Probably even less of an impact now, where the top 6 Conference Champions make the playoffs.
A revamped Big 12 would be solidly entrenched as the 5th best Conference, with a large gap between them and the 4th place Conference, and a larger gap between them and the 6th place Conference.
Agreed... But how big of a drop will it be? What happens to TV rights (and whether your game is televised)? What happens when recruits aren't going to be in big-game matchups against Texas and OU every year and their game will only be televised on the Ocho?
The B12 GoR is due for renegotiation as it expires in 2025, and Texas/OU have already said they don't plan to negotiate their rights in that renegotiation. B12 TV rights are about to take a serious market tumble. How excited are recruits going to be about your facilities when you're falling behind in that arms race?
Take Texas, OU, and for the sake of argument Kansas out of the B12.
Now you've got ISU, KSU, OkSU, TTU, Baylor, TCU, and WVU (who may be ripe for the picking in their own sense). Add some G5 teams like Houston and Memphis, SMU, maybe Tulsa or Tulane?
You don't think that regional recruits will be salivating for an Iowa or Kansas or Colorado or Arizona/ASU offer over those schools?
You don't think it's plausible that 15 years down the road, Iowa and Kansas' national recruiting rankings are 5-10 spots higher, while ISU and KSU's are 5-10 spots lower?
I realize of course that 15 years is a lifetime in college sports. Who knows--we could have three more realignments 15 years from now...
But I can't imagine that Iowa and Kansas wouldn't benefit from ISU and KSU being in a watered-down B12 while they were in the B1G.
