I've been in the coliseum in it's current state and it's pretty drab. The building is super old and dusty, and the ONLY place they've put any money in the past decade is in the main hall itself. All that really is is some tarps and banners hanging up around the mentioned practice courts. At least the courts are new. (Fun fact, the FMA floor from the 90's is in one of the gyms at the Blatt.) The weight room at the coliseum also reminds me of my high school's. It was just small and kinda dirty. None of it has the "shine" of the football, baseball, or even softball facilities which have all been built in recent years.
I get what people say when they complain about Basketball practice facilities. I would compare it to how our football practice facilities were in the Holtz era.
I'm of the opinion that the money that would be required to bring the coliseum up to par for a practice facility would cost as much as just building a new stand alone practice facility.
