To ensure the defender falls for the crossover before switching directions, the most effective method is by hesitating before switching directions. This hesitation can create the illusion of a more convincing move, making the defender commit to one direction before you quickly shift to the opposite side. The key is to sell the initial crossover well through body movement and timing.
Letting go of the ball can be risky and could result in a turnover, while avoiding eye contact might not effectively mislead the defender. Therefore, hesitation plays a crucial role in successfully executing the crossover.
