Just saw an old Morning Call article about the basketball team playing a game against Hofstra in Grace Hall during the 1984 season. It said it was the first time the team had played in Grace in 5 years. That would be 1979, when, I think, Stabler was built. I know it was recently renovated, so I am sure it would be a great small venue. Nothing like college basketball in a packed sweaty gym. If it held 1,500 to 2,000 for basketball, that is all you would need. 900 in that venue would at least give you some atmosphere and a home court advantage. Maybe do what schools like Villanova do, play your smaller games on campus (like DuPont Pavillion) then your bigger conference games off campus (for Nova Wells Fargo Ctr).
With wrestling and woman’s volleyball there, you would have to work around the other programs for scheduling, but you could certainly turn it around quickly for multiple events.
