I was curious about the whole lawyer thing myself. But as far as some of the ESPN/Fox info, I am hearing some of the same. Big12 was hoping to wait until finished analyzing the data, but the networks are pushing it hard to have an answer before start of next season (June/July). BYU has a big hurdle with their network. Cincy may not carry a huge market, but are decent in football and basketball to give year round ratings. UConn and Memphis were spotted for their basketball ratings (though UConn more than Memphis because of market size). UCF for their football ratings and the Florida market.
I do know the LHN is willing to become the B12 network while maintaining the LHN brand in Texas. They have to stop the negative cash flow and this is a way to do it. This makes it more appealing to networks as much of the infrastructure is already in place. The B12 conference championship game is going to be a no-brainer because ESPN is willing to pay for it.
Of course, I am only hearing all of this as a third party, so I don't know how official it is. But for what it's worth, I am in the broadcast industry.
