The hook shot is one of the most effective inside moves, but it is also quite difficult to execute.   A hook shot begins when the player puts his body between the ball and the opponent. He then releases the ball towards the basket with his outside hand in a "hook" motion (one arm out to the side and over the head toward the basket).   The test records the athlete’s hook shot technique and accuracy in simulated game conditions, since they perform in front of defensive Mannequins.
