NBA like in the National Basketball Association? You mean like the many European players that rock the NBA that are totally not Afro-American?
Maybe the issue is in how the selection is done in American colleges.
But I'm pretty sure the Afro-American population would gladly swap 50% of black NBA players to have 50% of them in the middle-class.
