I think there are two different debates going on here.
One, is whether the basketball product being put on the court deserves a rocking rowdy Carver environment? Obviously, that's questionable. It's on the athletic department to give the fans something to cheer about, but, at the same time, these players deserve our support. I get it, though, as fans the only viable way to force change is to spend our dollars elsewhere. I just hate to see the players punished as a byproduct of fan frustration.
Two, is Carver set up to be a great environment? Having been to many games there, I would say definitely not. When it was constructed, it was apparent early on that the goal was fan comfort, not visiting team intimidation. The lighting also is, for lack of a better word, "sleepy." And, as others have pointed out, the location of the student section is far from ideal.
For those that think it is a great environment, I would encourage them to go to a game at Hilton, or Indiana's Assembly Hall. Carver isn't even close, and is even a far cry from the old Fieldhouse. I sincerely hope that the department takes those things into account when constructing a new arena.
