I had the privilege of attending SU @ GT this past season. Sadly, Cuse lost.
However, it was in all other aspects a quality experience. The facility (McCamish Pavilion) underwent an extensive $45 million renovation in 2012, and is quite nice, although not particularity large (8,600) for a metro arena... it's in downtown ATL.
The crowd was really jazzed from the opening tip, but since this was my one-and-only time there, I can't say how much of that was because they were playing Cuse. Lammers took us apart that game. It seemed to me there were a LOT of Orange fans in attendance, maybe as many as 500, although that's purely a guess.
All-in all, it's a great atmosphere, but nothing close to a game at the dome. Obviously, the proximity of Hotlanta is a plus. Anyway, that's my experience of what GT has to offer a guy like Tucker in terms of venue.
