The video below shows a drill to work with your point guards–or any player who drives to the basket on getting to the paint and then backing out if necessary.
It is a good drill for any player who attacks the basket, not just point guards.
The drill teaches to bounce off when there is no play to be made, then re-attack–all the while the dribbler has his or her head up.
The video is 2 minutes in length.

There is a fine line between attacking the basket on the dribble and using the dribble to get into trouble. This drill helps you to be develop the skills you need to be able to not pick your dribble up until you have a pass or a shot.
