Silly idea.
All they have to do is argue for racial quotas and affirmative action.
That would ensure the NFL,NBA,etc, have the direct proportion of players according to race.
Meaning of course the NBA and NFL wouldn`t be 80% black anymore :-)
Better idea: Have an open league with a height restriction of 5’11”...
WHY do affirmative action laws NOT apply to the NFL and NBA?
