To control the ball, you must have a good sense of the ball. Practicing well is the most boring thing. Dribble hundreds of thousands or even tens of thousands of times a day (if you have patience).
Then, it is the strength of upper and lower limbs: lifting dumbbells, starting from a lighter, gradually increasing, pull-ups, these are good ways to exercise upper limb strength. For lower limbs, run, jump rope, squat with load, run stairs quickly, etc.
Then there is the ability of physical confrontation. You can ask someone to point a cushion of the right size at you, and at the same time you can do technical actions such as layup and jump shot.
After that, pass the ball. If you pass the ball well, it is definitely the team's attack. I can't give you any advice on how to practice. I still need to accumulate more practical experience. Anyway, we have to calculate the angle and landing point of the parabola of the ball in an instant. Direct pass should be passed to teammates below the neck and above the waist, and the ground must be solid. And it depends on which hand the stuck teammate holds out, which means you should drop the ball and hit it on his chest or let you hit it on the ground on his lower left or right. How to make teammates feel comfortable? Usually, you should communicate with your teammates more, which is also the degree to cultivate your tacit understanding.
Also have a full understanding of teammates' playing style and position. Some people can pass the ball without looking, and he can also pass it to his teammates. It's not that he is lucky, but that he knows the posture of his teammates and that they are sometimes or often waiting there.
Finally, spend more time learning how to pay attention to all directions and how to pay attention to the movements of opponents or teammates from Yu Guangzhong.
In addition, as a ball controller, you must never be angered by your opponent or the outside world. Learn to be rational about everything that happens on the court that is not good for you or your team. Otherwise, if you lose your footing, your teammates will definitely follow you. In addition to good skills, a big heart and outstanding basketball IQ are also necessary.
I hope it helps you. Good luck!
