And speaking of the Kohl Center and it's home court advantage, this is what it says on the UW website...
That looks like this...
PBA seems to have taken some similar ideas. There's no wasted space for walking paths or other nonsense. It's all tucked away beneath each layer (keeping the seats closer to the floor). And much like the Kohl Center, each level seems to rise right above the one below it, leaving a massive wall of seats, that are "right on top of the action".
Again, compare that to the Qwest, where they've wasted space on a hockey design, as well as rings of walking paths (green line) that push each successive layer out further and further. The levels aren't stacked nearly as tightly there as they are at PBA. And the upper-most level just goes back for days.
To summarize... I think the PBA design is great for basketball. With the building packed, it's going to be a fairly cozy place for a joint that seats nearly 16K. If we can get some crowd noise, look out.
