OK, same scenario as
in the OP, but with a few changes. Here, instead of the SEC, Oklahoma has opted for the Big Ten and its better academic pedigree. Missouri stays put. The SEC still gets a foot in the door in OK by tapping OSU, which despite being the lesser Oklahoma school is no mere consolation prize. And despite UConn's substantially greater athletic revenue, the ACC hands its final rose to Cincinnati, which offers a better balance between football and basketball.
