I assume this is prelude to working out whether all or only the vast majority of the MWC will be playing under the PAC name in a couple of years. I'd still be fine with bringing them to the B12 and having Yormark run the "Big Pac" or something and retain divisional play despite a large conference.
The antsy ACC teams are not going to stick around a moment longer than they have to, and ESPN/Fox have zero motivation to pay them more until they can do so without also giving more money to Wake and SMU.
