Why are most NBA stars black?

Personally, I think it's because blacks are more athletic. This is undeniable (relative to the yellow race and white race). Black athletes have a long career. Otherwise, why do you often see black stars Kobe and James dunk in fast break, while white athletes Nash and Parker lay more emphasis on layups in fast break? One more thing: at present, most black stars grew up in slums, such as Iverson and Garnett. So they spent several times more time training hard than normal white athletes, and a super all-around player like Kobe appeared. We shouldn't be surprised at the achievements of black athletes, they deserve it! The footwork structure of black people is conducive to jumping, and black people have strong explosive power. Various factors themselves determine that they are good materials for playing basketball. Super sports talent and diligent training have created great black athletes! ! !
