I am not so sure. The history of realignment says otherwise.
2005: USF, Louisville, and Cincy were added to the Big East from CUSA. And fairly, only Louisville of this group currently resides in a Power conference, but this is just to show precedent.
2010: Utah joins the PAC12 from MWC.
2012: TCU joins BIg12 from MWC/BE. Of course TCU was previously part of a power conference in the SWC. But again, they were a mid-major for 16 years before getting a bid.
2012: Louisville joins the ACC from the AAC.
These are just the modern examples of mid-majors joining Power conferences. And with BYU, UCONN and Cincy in the mix, it will just catalyze more G5 teams to play the P5 game in hopes of an invite. The MWC gets largely ignored because all P5 conferences, other than the PAC12, of course, are looking east, where the people are.
