Thanks for all the responses! Some very valid points have been raised.

One other reason why the ACC might opt for UConn over Cincinnati is $$$. In terms of athletic revenue for 2015-16, UConn raked in far more than Cincy (79M vs. 43M).

Suppose we take the original scenario and swap Oklahoma and Missouri? Along with its three little buddies, Texas still goes to the Pac, which will be friendlier toward some variation of the Longhorn Network than either the Big Ten or SEC. Missouri sticks with the SEC, while the Big Ten scores by adding the Sooners. Oklahoma State is far from a terrible consolation prize and gets the SEC into OK. Is all this any more plausible?
