The Pac12 teams are not going anywhere until they actually find out how much the next TV contract is going to be and where it will be shown. Everyone is just waiting for that announcement, and one has to think that since they keep pushing the date back, there just is not much out there for the league, otherwise they would have a deal done by now.
Letting this go on is great of the B10, they want the ACC teams, but will take but UW and UO, but they are on the backburner for now. It doesn't hurt or help the B12 either way, they have are at 14 for another season, then drop by to 12, by then, everyone will know how much the P12 contract is worth, and then teams will start to make their decision to leave or stay.
