Nothing ends the Big 12 faster than taking away from the interests of the higher valued schools, particularly Texas.
If you’re asking questions about LHN, the biggest one is what if A&M would have accepted the invitation to be included, as was the original plan. A&M stays, and then UT doesn’t have to move because A&M is using the SEC brand against UT
But in the end it wouldn’t matter much. The fundamentals support consolidation. The networks make more paying for the schools of value all in one or two conferences, rather than paying 12 schools to get 3 or 4
At best, maybe the P5 survives another round if we increase inequality, but eventually the top schools will be lured away imo
