I do think that wriggling 3 pac12 schools away (Colorado, Arizona, ASU) and picking UConn over Utah due to market / BYU’s protesting is very possible. I doubt the Big 12 would want WSU / OSU and chances are the most valuable brands are out of the big 12’s reach.
With that said, I agree UConn + 1 pac12 school is not logical. Neither is adding UConn with another g5 school. UConn by itself is vaguely possible if they like us enough & the pac12 contract is satisfactory, but I tend to agree they would have added us already if they wanted us so badly. 13 is also a clunky number, although it can be worked around. We will know very soon what will happen.
