Are OSU/WSU enticing to any conference at this point? Sure, the MWC commish's comment is probably just for leverage, but if they weren't close enough to add travel partners for Cal/Stanford, I don't think they'd be anyone's radar. If it weren't for Cal/Stanford, I'm sure Memphis/USF/Tulane/UAB/FAU would be higher targets for the ACC if their conference implodes.
And once the best teams in the ACC leave, you're mostly left with a bunch of 1-sport schools. At that point I'd hope to see a more regionalized reorganization between those leftovers, The American, the MWC, and maybe some of the top CUSA/Sun Belt schools.
Of course, that won't happen, so I'm still hoping we position ourselves to be part of the Pac-12's reorganization.
