The Warriors don't practice good shot selection. Make or Miss, they're going to run and jack up threes with 20 seconds left on the shot clock before the defense is set. Over the course of 48 minutes, a team like Dallas is going to practice better shot selection than a team like the Warriors. The best thing to do is have Dirk get the ball on the wing and take a two-step pull-up jumper, not set up on the low blocks and try to post up a smaller defender. He has weak post-up moves, he's at his best playing like a two in a four's body, which is what he is. When he posts up, it allows him to get swarmed by double teams.
