We already did when basketball used to be all white, same with baseball
Now lets not be silly, if getting a job was the same as getting into the NBA there would not be these questions about diversity. The NBA is not just picking people based on their skin tone but based off of their actions in other games not just their resumes. The NBA does try to get more diverse players as well and every few years they bring out the next great white hope or Larry Bird.
Sports in general are just a bit more transparent when hiring players than most other jobs. It can be very clear who is the best player or has the better skill set. The same is not true if you have two resumes that look the same.
