Just look at the number of white pro bowler by year. The trend is pretty obvious. Even as far back as the 60s every educated person knew football was bad for the brain. CTE is not a new discovery, people even knew about it hundreds of years ago, they called it punch drunk. Consider the trajectory of poor white people in inner cities. Decades ago it was poor Italian, Irish, ******, etc. immigrants that filled the ghettos of inner cities. Those people had 2 options crime or sports. Now those areas are populated by blacks and hispanics.
