Steve Sailer reflecting on the big three American sports and their relative popularity (football and basketball on the ascent, baseball on the decline) includes this graph from John Rivers:
The correlations between the racial composition of the total US population and the racial compositions of the populations of Major League Baseball, the National Football League, and the National Basketball Association are .97, .14, and .08, respectively.
Baseball looks like America, but that’s only an interim objective for institutions and organizations that are whiter than America at the point of consideration. Looking like America is better than something embarrassingly white like hockey, but it’s not good enough. Because the NFL has too many white quarterbacks and coaches (and kickers, too, but it’s better that way since kickers are targets of ridicule whenever they try to do something athletic like tackle a kick returner), the NBA is the most vibrant sport.
