I think UMASS could be an option if they can get their hoops support back to what it was in the mid-90's. I think their arena seats over 8,500 but they're only averaging about 3,500 per game.
They would help bring in another large market to the NBE, they have both men's and women's Lacrosse, and they're considered a very good school academically (although they are public as well).
I did forget about LaSalle - pretty good history - I could live with that. I assume 'Nova would get turf conscious though. I am a supporter of SLU as they have built the infrastructure, literally, of a successful program and they have their version of Dick Strong that helps a lot. I know they have some drama going on there with their administration etc., but I do think there is potential for big things there - if not them, Dayton would be my choice for a Midwest addition.
Georgetown doesn't see Richmond of as big a threat to their recruiting base as VCU.
No clue who another quality eastern team would be. There just aren't any.
