This basketball ball screen drill is all about learning how to score off of the ball screen and a big part of that is reading the guard defender and exploiting whatever decision that they make when guarding the screen. You are going to work on two different ways that the defender is going to guard the screen in this drill. The first way is by going under the screen, when this happens the ball handler is going to work on stopping behind the screen and shooting the ball. Secondly the guard defender is going to down or blue the ball screen and try to deny the ball handler from even having a chance to use the ball screen. To exploit the defense on this type of defense the ball handler is going to fake like they are going over top of the screen, refuse the screen, and then split the imaginary post defender that is sitting on the baseline for a little floater in the paint.
