Im not sure thats a given. Dayton would be leaving a stable conference and joining a conference that has, for the better part of 15 years, been ransacked with instability. I dont think UD and
XU would be in a position to "join" a new Big East. Rather, the Big East would be the ones being forced to ask for contrition.
The A10 may be in a great spot. They may be the prime destination conference where everyone seeks stability. That might mean a couple teams like
LaSalle and
Fordham eventually go to lesser leagues to make room. But I see the A10s long-standing stability and ability to grab schools from the Horizon, CAA, and MVC as a sign of that strength.
The BE schools will be on an island by themselves. Too small to exist on their own. Too large to separate. The only exception might be DePaul wanting out. They have struggled in the BE for most of their membership. Marquette has always looked down on Dayton. ND even more so.
