Pipe your ass down. Eventually they will. Not being divisive cause I'm carribean. Looking at the facts, dominance in a sporting field is based on:
1. Genetics. We share that but Africans have a higher genetics diversity than us.
2. Training. That can be gained with money as they develop.
3. Nutrition. Same as above
4. A large pool of potential athletes to pull from. Sub Saharan Africa would have about a billion black people.
So the 4th point is where they will dominate us if all others points goes well. Having more trained people to draw from all else being equal is hard to beat.
Just imagine if eastern Africa with all them nilotic and other tall brehs start playing basketball seriously and get the right training
