I find it unlikely that ESPN/Fox step up for another $120MM a year to the Big 12 to add 6 teams. The extra inventory is just not worth that much to ESPN/Fox, who both already have a lot of inventory. I think the only network that would be willing to go anywhere in the ballpark of $20MM a school for new programs is NBC or CBS/Turner, because they don't have any product right now so the incremental is worth a lot more to them than it is to ESPN or Fox.
People keep benchmarking off the wrong data points. The ACC, Big 12, B1G, SEC and Pac 12 are not expanding, Fox and ESPN are. Likewise, NBC and CBS/Turner seem to have at least a passing interest to increase their presence in this market, and could be major players in any future expansion decisions. There is an idiotic notion among a few on this board that some school would turn down more money to stay in the league they are currently in.
As of this moment, it appears that the Big East is still well positioned to take advantage of NBC's and CBS/Turner's (assuming they work collaboratively) desire to get a larger position in college athletics. NBC, CBS, Fox and ESPN's interest in the constituent programs of the Big East and their desire for more inventory is the ONLY meaningful factor in UConn's athletic future. Everything else is noise.
