The ACC wasn't built to have a cable network. It was designed to maximize over-the-air advertising and basketball. With over-the-air revenues declining and basketball becoming less important, they find they have the wrong schools for a world in which conference cable networks drive revenue. They have to accept lower revenues. That's OK for most ACC schools, the likes of BC, Pitt, Syracuse, Louisville, Ga Tech, Miami are really middle-tier schools who deserve middle-tier revenues.
The Big XII isn't really built for cable networks either, except for the state of Texas, Oklahoma, and Kansas, which is pretty limited -- less than a tenth of the country.
If they have to have the same revenue as the B1G, SEC, and Pac, then the Big XII and ACC could rearrange themselves into a "best of" conference with a western division (Texas, Oklahoma, Kansas, Texas Tech or TCU or Baylor, Ok State, Kansas State) and eastern division (UNC, UVa, FSU, Miami, Clemson, Ga Tech) with Va Tech going to the B1G, and everybody else forming a "Big East lite" like we would have had if the Big XII leftovers had joined the Big East a few years ago.
On that rearrangement, UConn either joins the B1G with Va Tech or joints the "Big East lite" with BC/Cuse/Pitt/Ville.
