If you watch good ball handlers you will recognize that they do a great job of staying low while dribbling the ball. They are able to change the ball from hand to hand quickly and with ease. All of this comes from being comfortable with the basketball, and being equally confident with both hands.
This dribbling drill is going to work on staying low, handling the ball, and developing good footwork. If you are a primary ball handler this drill is a must and something you should do regularly. This is great basketball drill to do on your own, in small group training, or in a camp setting.
