Build it downtown. It's a 5 minute walk for students. Hell, a downtown arena would be closer to Grant Hall, Gallucci, Exchange, and 22 Exchange than an arena bordering Rt. 8 would be. Plus, there are bars for people to go to before/after the game. A stadium is a different monster, people hang out and tailgate all day, then go to the game. All in presumably nice, cool, fall weather. Basketball games- people show up, and hit the bars before or after the game. The weather sucks here in the Winter. No one is going to want to walk downtown to celebrate the big win if the arena is a 20 minute walk from downtown.
