What would you be doing right now?
This Big East thing could still go many different directions, but you obviously want to get some/all of your old teams back into your conference.
The schools that just left C-USA could try to stay where they are and grow the Big East, in which case you can't get them back. But, what would you do to try to get them to leave the Big East (or whatever it will be called) and come back to C-USA? Keep in mind the tricks that other commissioners play.
What would you do? Give a few details explaining why you would do it that way.
