This is one of the goofier things I've seen in a while. There is literally no reason for Jackson to twirl a full 360 degrees after firing a pass to Boris Diaw. Look at his feet. You can almost see the neural impulses traveling down: rotate, rotate, rotate.
The worst part is he doesn't even get credit for an assist because in all that thinking and spinning he must have over-rotated or something, making the pass just behind Diaw enough that it ruins a gimme layup. Diaw was forced to readjust and dump it off to Tim Duncan.
