I don't believe the PAC was close to adding UH & TCU. I think someone is putting it out there to bolster their school's image.
Honestly, I don't think any of the remaining 8 had/have offers to the other 4 leagues. Why? ESPN could have placed all 8 schools in the ACC & PAC and maybe two to the SEC if they needed or possibly one spill over to the B1G. The remaining 8 schools would have taken placement in an existing P4 with long term contracts or a handshake of what the PAC upcoming deal would have been in lieu of exit fees and any GOR guarantee of the last two years OU & UT leave.
Part of the revenues needed to pay everyone could have been paid by conference networks getting carriage in Texas if you put Baylor/TCU/WVU in the ACC and TT/OSU and maybe UH in the PAC. In this scenario the PAC either takes a 4 team group of TT/OSU/UH/KSU and if its 6 teams KU & ISU. If 6 are too many, I could see where the SEC could have been convinced to take KU & ISU. Maybe the B1G could have taken KU & Colorado and ISU was #6 in the PAC.
If the other leagues were at all considering the remaining 8 schools, then ESPN/FOX don't have to give Cincy, UCF, UH a big raise(although UH may have moved up due to the Houston mkt) and BYU also costs more. The only way these schools and possibly 2-4 more getting a big raise is if 72-80 schools are forming a new division 1 and there are no more games against FCS schools or current G5 that don't make the cut. Meaning they need the inventory of games and the value of better games is worth that to the networks. Its also possible some schools with budget problems or future concerns of NIL ramifications or even more controversial things coming up like players as university employers want to exit the top tier. Schools like WF, BC, Vandy, WSU, Oregon St., Cal are just a few. Some feel if players are classified as employees some schools that might surprise you will even move down.
