Hmm. CBS Sports broadcasts MWC contests. Would expect anything else emanating from the Big EYE network?
What network is going to commit to any dollar amount when they have no idea who will be in the conference tomorrow? Outside the Big 5 conferences, you have UConn , Cincinnati, Boise, and BYU, that may have some significant worth to the networks. Too bad those four can't come together as east/west anchors of a 12 team all sports conference.
There are some obvious other choices but those four would serve as your anchor schools.
