Actually, I have to admit that dead-on center court, absolute front row of the upper deck (so that's actually below the entrance to the upper deck) is a very nice seat. Nobody in front of you, just the rail, kind of steep viewing angle but acceptable (and interesting perspective), not so far from the floor as to make the game "too small" and best of all, directly in the center of a row, so nobody moving across in the middle of the game to go get food, etc. And quite a bit cheaper than the lower deck, where you get various reasons for obstructed views.
I shouldn't really give that secret away. In fact, yeah everything in the upper deck is terrible.
