Just noticed:
Behind the AUS basket is a solid bank of dark red seats, all empty.
Behind the US basket is an active area with a walkway and large floor area at parquet level, generally white in color, with cheerleaders moving around and jumping etc (not at floor level but up one level in the arena). All this makes for a *very* busy background, lots of 'noise' and movement in line of sight when you're trying to shoot from outside.
I'm hoping the USA gets hot at the other basket in the 2nd half. Looks much easier from a shooters' standpoint. You don't often see KML draw air.
