A) is wrong though. The ACC made about $31m in 2022 in media rights. The new Big XII will average $31.4m for 6 years (presumably crossing that threshold in 2028). Basically 6 years behind the ACC contract.
B) I honestly think is less of a concern. ESPN had pac money set aside that wasn’t spent in 2022. They used it to shore up the BXII. That won’t be the case in 2030. Instead the BXII will be going to open market with a handful of G5 schools in the East and BYU/Utah in the West and the rump of the old Big XII in the middle. ESPN would find it cheaper to send Ok St, Kansas, Arizona, TCU to the ACC than pay $150+m for Central Florida, Colorado, Cincinnati, and BYU.
I also think Clemson has been fine with the on-field run this past decade and aren’t pining away for more Oklahoma regular-season matchups. They simply want money. It’s the B10 and SEC they dream about, not the BXII.
