Yeah, UConn and Maryland are about on equal footing to me as far as football is concerned, with Maryland having a bit better history, but not so much to make the loss hurt. When it comes to basketball, however, it's night and day. ACC adding UConn and losing Maryland would be a win/win.
The ACC is in a position to being one of the major conferences or really hurting themselves if they end up losing some of their better football programs. If they're somehow able to convince Notre Dame to eventually be a football member too with the way the college landscape is going, then they'll be fine.
