When dribbling through traffic in a basketball game you are not going to have time to plan out what move you are going to use to get through it. You simply need to be able to see what is going on in front of you, and then quickly react with the right move. It may be a crossover, a reverse between the legs move, etc.
That is why you need to be ready to make the right move at the right time with having to hesitate. This basketball drill is designed to be able to help you work on dribbling through traffic with any move. After you have finished off of the dribble though you are going to be required to score off of 2 pin down screens. This is all part of learning to move without the basketball and becoming a complete offensive player.
