As for Stephen Jackson I look at it like this. He was part of a championship team for the Spurs before and knows they're system. A team like the Spurs are made up of talented veterans who can play Pop's system. Jefferson was never able to play well in Pop's system and he failed defensively most nights. So its at worse a wash trade wise. As for RJ he is just another defensively challenged player on the warriors. Also RJ's deal is a year longer than Captain Jack.
