Saying black people are more athletic than whites won't be an accurate assumption at all, though the media have always tried to make it appear so. The media keep hammering on the athletic nature and abilities of black people over their equally or even more talented white counterparts.
In my opinion, this is not a very fair generalization. The truth is that black people are known to dominate certain sports because they grow up loving such sports, keeping to the rules and principles of their sports of choice and train very hard to get to the top.
Genetically, white people are not more skate or fit to play hockey. Hockey began in suburbs where the populations of blacks were quite little. In the United States, where several urban black men and women are still economically impoverished, free basketball courts is obviously available and becomes the sporting activity of choice. Those of them who end up as NBA stars grew up training vigorously and rigorously to excel in the sport.
Soccer remains one true global kind of sport, and you can find just as many great black football stars as you can find their white counterparts.
