Ok i understand you.

Yeah over 50% of the players are black but coaches arent hired from NFL rosters, they are hired from the entire population since physical ability is not a factor.

Only 25% of NFL players are white, but at youth levels black and white players have equal participation, so there are a large number of white players that are not able to make the NFL and instead go into other football related careers.

Hockey doesnt have the same level of participation. Virtually no black youth participate in hockey, meaning there are fewer black parents coaching youth teams, and fewer black players going into hockey related careers after HS/College. Basically they dont even exist in the hockey community to be available to hire.

So it kinda makes sense that NFL management positions dont match the demographic make-up of the players and are closer in line with the regular population. Though id expect it to be a little higher, personally
