I don't see why they would want to join the Big East. The AAC as bad is it is would only lose Houston if the article is correct. It will still probably be the strongest football conference outside of the Big 5 and with Memphis, Cincinnati and Temple, Tulsa and SMU it is not that bad a basketball conference. The University of Connecticut has been doing just fine in that conference.
I think the next great wave of expansion will be a race to 16, so the AAC will eventually be ripped apart. Memphis and Cincy will eventually be gone. UConn is in a tough position, tougher than I think a lot of their fans realize.
As I've posted before, the attractiveness of their men's and women's programs (in a league of its own) coupled with the fact that their football program draws better than Duke's, makes me think the ACC (overall not a football powerhouse) will eventually be embracing them ... and that's something I would absolutely hate to see.
