The in and out crossover move is a great dribbling move to use against a defender, and if mastered it can be very hard to guard. It is what is called a combo move, because you are combining two moves together. As soon as the defender goes to cut off the in and out dribble, you are immediately going to cross the basketball over and go the other direction. This wall tennis ball drill will help you to work on the move and make your hands lightning fast. Basketball drills like this are also great for working on hand coordination and quickness.
