Right now all options are in play for every P5 conference, but the ACC and the B12 are leaky boats and there appears to be only one network available from the marketplace and it requires more and better content from whichever league gets it first.
There will be pressure for each league to get its agreement done before the other. The first domino will create chaos whether it's the B1G, B12, UT, OU, FSU or the ACC that pushes it over. An extra $10M per year will get any of these schools to jump.
The question is will there be a next domino & when? It's easy to say "of course the SEC & B1G will expand" because expansion means more dollars. At this point, they have created such a separation between themselves and the other 3 conferences that they now make the rules. They can decide when & for the most part with whom they will add when the time comes.
While we have all been saying that the 1st conference between the ACC & B12 to get a network is the one who survives the stark reality is that in order to start a network someone needs to finance it. If neither Fox or ESPN are willing to pony up the cash necessary then there are no new networks. FOX is already contracted with the B12 & is going to have 50% of the B1G broadcasts going forward. ESPN shares the B12 with FOX and owns almost all (except for Raycom) of the ACC. Why would either of them commit more money for a network when they already own the rights?
While UConn desperately needs something to happen, there is more of a likelihood that nothing happens and the status quo remains
