I'd think you'd have to nearly sell the place out to make up for the cost of renting the arena compared to using the free one on campus. Also, i'm not sure what the atmosphere would be like w/ 10k people. while a lot of ppl, it could feel dead bc the building is so much bigger
Also, I do wonder how much the pegulas would embrace it. They are very supportive of UB athletics, but there is a limit to that support - at the end of the day we are competition for them.
