It's a great wish, but where is the funding coming from?
Or the real estate. No way you can put a 10,000 seat arena in the current footprint of Carnesecca Arena. Or fit the extra 1,500-2,000 cars that would result. Or get them on/off campus. But you dont need to. Villanova just re-did their on campus arena, capacity 6,500. We dont need a bigger venue, we need a better one that's a similar size. (Oh, btw...that Nova facility upgrade? $65 million.)
I'm not against the "demolish CA and start from scratch" part of the plan. But thats 5 years away, minimum. And even then, the only way its happening is with consistent trips to the dance (and the increase in revenue that results from sustained success), then using the excitement about the program to do major alumni outreach and fundraising.
Having every BE game at MSG sounds wonderful in theory. But the fact is, a major reason why we could do that in the old days was because there were plenty of local Syracuse and UConn fans to help fill the building. Playing Xavier, DePaul or Creighton in front of 6,500 isnt exactly a magical MSG experience. I'd much rather play them on campus in a brand new cozy 6,500 seat arena that has actual seats and concessions that dont look like my kid's CYO games.
