You have to think about folks coming in from out of town. There is NOTHING on campus other than the game. No place to eat, drink, hang out. I was at the 2004 Frozen Four in Buffalo and it was a disaster because, at that time, there was nothing to do around the arena.
If you insist on holding this at Alumni, better make sure the air conditioning is working, and you will need to build a "TBT Village" nearby with food trucks and beer tents. Otherwise it needs to be in the city. You can promote UB all you want during the telecast. It doesn't have to be at Alumni. It's simply not the best venue.
