This is a weird statement. Why would Fox over pay to keep Texas away from The Big10? If the rumored move is true, Fox will be overpaying for The Big10 and having Texas, along with Kansas and Oklahoma (assuming that's the case) would wind up saving money. The ACC I can see, but I would think Fox wants Texas to go the Big10.
I just see The Big12 as a dead conference walking and will cease to be a P5 conference in the next 7-8 years. The main parts will be gobbled up while the dregs (Baylor, TCU, ISU, OkieSt, and KSU) will be left to their own devices.
If the Big 12 does disband here are the following ways I see could happen:
1. UT and KU to Big 10; OU and WVU to SEC; TCU and Baylor to ACC (ACC would get into the state of Texas and two good football programs); TT, UCONN, UH, Memphis, UC, UCF, USF, ECU, KSU, ISU, OSU and BYU form new conference
2. UT and OU to Big 10; WVU and KU to SEC; TCU and Baylor to ACC; new conference same as #1
3. UT, OU, TT and OSU to PAC; WVU and KU to SEC; Baylor and TCU to ACC; ISU and KSU to American Athletic Conference
4. Same as #3 except replace Baylor and TCU with ISU and KSU
5. UT, OU, TT, OSU to PAC; WVU and ISU to ACC; KU and UCONN to Big 10; KSU, Baylor and TCU and Houston to Mountain West
6. UT, OU, TT, OSU to PAC; WVU and UCONN to ACC; KU, KSU, Baylor, ISU and TCU with Houston, Memphis, Cincinnati, UCF and USF form new conference
7. UT, OU, KU and TT to PAC; OSU and WVU to SEC; Baylor and TCU to ACC; KSU and ISU to new conference
8. UT, OU, KU and TT to PAC; WVU and UCONN to ACC; KSU, ISU, Baylor, TCU and OSU to new conference
I don't see any other scenario. No conference is going beyond 16 (except ACC if ND remains steadfast to independence). If Texas, West Virginia and Oklahoma aren't available cuz another conference gets them then I could see TCU and Baylor being looked at. The ACC could go to pods with TCU, Baylor, Florida State and Miami in one pod, GT/Clemson/NCSU and WF in another pod, UNC/Duke/UVA and Virginia Tech and finally Pitt/Cuse/Louisville and BC.
