I'd like to see the Big East amicably split along geographic lines. The five Midwestern schools - Butler, Creighton, DePaul, Marquette, Xavier - would be the core members of a new conference that would also include current A-10 members Dayton, Loyola (Chicago) and Saint Louis, current Horizon League member Detroit Mercy, current MVC member Valparaiso, and current WCC members Gonzaga and Saint Mary's (which would kill the legitimacy of the WCC). This would be an attempt to form a basketball-centric conference that is largely Midwestern and of comparative strength to the Big Ten. ESPN can use this new conference to replace the Big Ten during basketball season.
The Big East would become a Northeast-only conference, adding Duquesne, La Salle and Saint Joseph's from the A-10 and Iona from the MAAC.
The loss of 6 members as a result of the Big East split would be particularly harsh on the A-10. The first Big East split cost them three members (Temple to the American and Butler and Xavier to the new Big East).
