I've yet to see the most obvious answer.
Basketball is a sport where explosive athleticism is a major advantage. Sure, developed skills are extremely important too, but I believe (and it seems patently obvious, just look at Olympic sprinting and jumping events too) that when it comes to explosive athleticism, blacks are at the top of the food chain.
If all other skills are equally developed, but the black athlete is more powerfully explosive, he's got the edge, hence greater representation in the league. It's a league about winning, so they'll take whoever gives them the best chance to win.
No sense tap dancing around it, looking for every convoluted answer but the obvious one. Occam's Razor applies here. Blacks have greater explosive athleticism.
Then please explain to me why blacks don't dominate hockey and soccer, two sports that also require explosive athleticism.
Who says they don't dominate soccer? There's a world outside America. Blacks are largely overrepresented among elite soccer players, even though soccer doesn't require the exact same traits basketball or sprinting do. They probably don't dominate hockey because they don't play it.
This is not unique about basketball in America. Blacks are generally over-represented in every sport that requires some physiological traits as long as the black population plays that sport.
And yet only 4 of the top 20 highest paid soccer players in the world are black. Also, Brazilian and other dark latinos are not necessarily black but are naturally dark because their native inhabitants were dark skinned. In American basketball, blacks dominate the highest paid players and the top players amongst the top 3 strings All-NBA teams, they do not dominate basketball world-wide.
You say blacks don't play hockey, but why is that? It's because it is too freaking expensive to play for mostly poor black American youths. Black American youths don't play soccer because soccer isn't made available in the mostly poor black areas because there isn't land available to make soccer playing fields available. Again it comes down to money.
I am not arguing that black American athletes don't have phsysiological differences and advantages over their white counterparts. But, the reason so many of the best black athletes are playing basketball is the economic situations and lack of diverse offerings of other sports to them in America. If black American athletes were introduced to all sports in the way they are to white Americans youth then more of those athletes would be playing other sports and there would be more spots available for other ethnic players to play NBA basketball.
I honestly believe that if there was a skating rink in every neighborhood in America and it was inexpensive to play hockey, blacks would populate the sport to a dominant degree and that it would leave many of the professional spots in the NBA open for others.
Actually, I have to refute the statement that I highlighted on bold. The fact is that out of all the African slaves that went to the Americas, 41% went to the Carribean (Jamaica, DR, Haiti), 38% went to Brazil and only 4% went to USA (I saw this on a history book back in 8th grade). Brazil actually has the third largest population of black people in the world (meaning african and african descendants, including Africa itself). So Brazil actually has more black people than most African countries, which is largely due to the population size.
Also, these are statements based truly on observations only and previous "hear say" knowledge that seems somewhat believable. However, when we say black people, we have to be able to differentiate which part of Africa are the black people coming from. For example, we say that they are athletic, but that is not true to with Kenyans, which many have strong aerobic threshold but are not strong by any means.
For example, I think there is a difference of looks from the Brazilian blacks and American blacks (I am talking about true blacks since Brazilians have a lot of mixes). American seem stronger, bigger, and faster. That may come from the part of Africa the slaves came from. There's one region of Brazil where most of the slaves came from one region in Africa, and they say that the Africans they enslaved actually had slaves themselves and were known to be pretty "lazy" and were always finding ways to get out of work. They say that that culture took over the region and now the stereotype of those regions are that people are lazy. Now, the slaves from the southern region (Rio de Janeiro, Sao Paulo) came from the West Coast of Africa, where the culture was a little more advanced and the African were more physically fit, and coincidentally, a lot of the Brazilian black athletes comes from these regions.
I don't believe that to be the truth, but when talking about genetics, I do think that may play a small role. The people that live the mountains of Peru and Chile have been known to have a more efficient oxygen uptake and usage than the world due to their region. I can see how generations and generations of African from a certain region could be more susceptible of having more fast twitch muscle fibers than the rest. In the end though, it's all about playing the sport and practicing the sport. Basically, the more of a specific population playing that sport, the more likely someone will succeed, just like California and Texas have more athletes than Alaska.
