How to keep the ball from being broken when dribbling under the leg and preparing to pass the ball? What should I pay attention to?

Pay attention to lowering the center of gravity when dribbling, and then master the speed of dribbling, which is related to your proficiency in dribbling. Then there is your own reaction speed.

Generally speaking, when the body's center of gravity is low, it is rarely broken, because others are trying to catch your ball at the same time. Once the ball is missed, it means that he has been caught. Therefore, no matter whether it is a normal game or a formal game, few people will take the initiative to catch the ball except Kobe.

To sum up, protect your ball, don't think about how to stop him from breaking through, just think about how to pass the ball to him, and attack is always the best defense.

Good luck!
