As a martial artist and a big NBA fan, I think that there can be many uses of Judo in the NBA. The very first thing you learn in Judo is how to fall correctly, and how to minimize damage on the body while doing so. You practice break falls, both side and straight back. The next thing you learn is rolling, many such techniques used in Parkour.
I think players should invest time in learning these techniques. Example: Rule 1 of break falling... never break a fall with your wrist. Ahem, Delonte. By incorporating such techniques, I feel that players can have greater longevity in the NBA, protecting joints such as knees, shoulders, wrists, and minimizing damage on the neck and spine (TJ Ford's injury would never happen) when they tumble... and they do crash to the ground a lot.
Not only is this a benefit to the players, it's a benefit to the owners as well. It'd be like investment in protecting assets.
Anyways, just a thought.
