Start off with your players dribbling the ball on one knee, they should be dribbling the ball with their strong hand. In order to teach them to keep their heads up while dribbling the coach will flash a number (1-5) with his fingers and your players should yell out the number that the coach is flashing. Progress with this drill from dribbling on one knee to standing and stationary dribbling with their strong hand and alternating with the weak hand and then to moving with their dribble.
