Let's suppose that in 2025, the ACC, Big Ten, SEC, and PAC take advantage of the expiration of Big XII GoR to expand to 16 each, and pick apart the Big XII.
PAC will have 4 openings;
SEC will have 2;
Big XII will have 2;
ACC might take in Notre Dame as full member (#15) and then one more.
My thinking is that ACC will take in Notre Dame + either UConn or WVU.
The PAC / Big Ten / SEC would then engage in a free-for-all with their remaining 8 invitations.
It is NOT a slam dunk that all 8 invitations would go to current Big XII schools.
Certainly Texas, OU, OSU, and KU have appeal.
KSU and Texas Tech to a lesser extent.
WVU could be a nice addition to either ACC or SEC.
I think RIGHT NOW, BYU and Houston may be more attractive expansion candidates (in terms of fan following / TV markets) than
Baylor, TCU, and Iowa State.
If we go to 4 "P4" conferences, I see BYU plugging into ONLY the PAC, and only in certain scenarios.
There may be a scramble by the numerous conferences to grab Texas.
PAC and SEC might both be interested in the Oklahoma schools.
If the PAC's first choice is UT-TT-OU-OSU, but it doesn't work out,
BYU may be part of PAC's "Plan B".
As Homloe indicated, BYU's mission should be to have more on-the-field success,
to enhance BYU's attractiveness before the next round of realignment.
Maybe they tweak their Honor Code during this period....
