Dribbling One-Ball. Windmill. This drill is just the reverse of the "Butterfly". Bend at the waist and knees with feet wide apart. Bring the ball backward over the thigh and dribble it from behind through the legs and catch it in front with the opposite hand. Bring it over the top of the opposite thigh, behind the back and dribble it forward through the legs, catching it with the original hand. Go as fast as you can!
