First of all, people who deny racial differences are amateurs. Some people will take Liu Xiang and Yao Ming as an example. Let me start by saying that since Yao Ming is a center, not a defender, there is a big difference here. And there is a very detailed question, that is, why did Yao Ming gain weight after entering the NBA? Because, as a result of the center's weight gain, he can pull his opponents in the same position back into the air and then invent his own advantages by technical touch. However, this undoubtedly shortened my career. Some people say that chinese basketball association caused Yao Ming to be overtired, but I don't admit it. But what is Yao Ming's injury? Stress fracture of toe root. Look it up, you should understand how much pressure Yao Ming's weight has put on his feet. As for Liu Xiang, the outside world basically doesn't know how much exercise Liu Xiang takes in a year at its peak. This is invested by Shanghai Sports Bureau and State Sports Bureau. This kind of cost can't be borne by any individual in a team project, and the development of American basketball games doesn't need such a grand investment at all, because of the difference of physical talent.

Let's talk about technical problems first. Externally, what you can see is that the arm span of black people is generally long and the dribble is good. But the reason behind this is that due to the length of the wingspan, when bringing the ball to the black player, the trajectory of the ball is less, including the finger is longer than the palm, which extends the control ability of the ball.

We all know that when you want to speed up, the demand lowers the center of gravity, but how many people know that lowering the center of gravity to a certain extent will affect the speed? This is because there is not enough strength to support it.

An Asian player, due to the problem of wingspan, can only lower his center of gravity in order to control the ball more stably, but he can control the ball stably at a certain level, but his speed is also lost. On the contrary, because of the length of the wingspan, black athletes don't have to lower their center of gravity so much.

However, race leads to the higher content of red muscle in Asian muscles (endurance, stable and precise muscles), while the content of black white muscle is relatively high (affecting productivity).

Therefore, this racial advantage is a problem that cannot be ignored.

Second, the system. Since the victories of Bater, Wang, Yao Ming and others, China has generally trained big-name players in the selection of candidates. When selecting candidates, the Central Sports School does not look at speed and fundamental merits first. It depends on your body shape, and then you cultivate it. Moreover, cultivation does not start with some basic skills of defenders. They all become shorter at a certain age and can only play as defenders. In other words, it is impossible for China's current basketball selection system to have talents like Thomas Jr. and nate robinson.

Guo's appearance was China's hope that the selection mechanism could be changed, but if it weren't for his family's basketball background and if he was a child of an ordinary family, he couldn't stick to his own style until now.
