This is one of the better defensive basketball drills that a player can do on their own, or with a small group of players. The reason why it is such a good drill, is because it is going to work on several different basketball specific movements, and it is also going to teach the player how to be efficient with their movements. This is also a great basketball workout for developing a players conditioning and teaching them to think when they are tired.
The 4 cones defensive basketball drill is going to work on closing out, defensive slides, back pedaling, and opening up the hips when turning to change directions. During the course of a game a player is going to have to go from doing one motion like back pedaling or closing out, into another completely different motion, and the quicker and more efficient they can change actions, the better.
