Making a good scoring move is all about being able to read your defender and then make the correct move before they can recover. This shooting drill is going to work on using a screen to get open, reading that the defender is being too aggressive on the chase, and then using a dribble to create space for an open shot.
The players that are really good at this type of move are able to read the defender before they even catch the ball. This is what allows them to exploit the defender. With this drill you will be able to learn the correct footwork and movements that go along with executing this move, as well as be able to get a lot of repetitions at the move in order to develop confidence.
