Not sure if you mentioned 2 from a posturing perspective or we only want 2.
If you look at current Big12 revenue on a school basis, it is all pretty even (within $15M) once you exclude UT & OU.
Same goes for the 3 new Big12 schools if they had Big12 TV contract vs. AAC.
Pac12 AD revenues for CU, UU, ASU, UA, Cal & Stanford are all in the same range as the existing Big12 members. So if those 6 teams are available- all 6 are no brains to add to Big12.
That would get us to an 18 team conference. Then I think we sit tight for a decade to see if the ACC GOR implodes.
