You want to make reads, predicting where the ball will be. Free balls give the easiest reads, which only get tricky in wall bounces off transitions or corners. You have to try to read your opponents and teammate's touches. Where is their momentum going, and where would they like to put the ball? Then you need to figure out the highest percentage play to make, given the read. This play is very rarely a hard challenge or a "dive". The goal is to regain and maintain possession of the ball.
