Why are most football players black?
<|assistant|>
In the US, football has traditionally been dominated by black athletes, mainly because of the historical and systemic discrimination against black people in American society. In the late 1800s, when the sport was gaining traction, racial segregation kept black athletes out of many colleges and universities, making it difficult for them to pursue athletic careers. As a result, the sport grew up mainly as the domain of black athletes, who later formed some of the NFL's greatest teams and players. Racial integration only truly took hold in the modern NFL era beginning with the merger between the NFL and AFL in 1970, leading to an increasing number of white players on football rosters. Today, despite the growing number of white football players, the overwhelming majority of players in the NFL are still black.
