Boxing takes way more head trauma than Football which is also very bad, but not like boxing, the rate of people alzheimers and parkinsons is way lower in football.

The thing is that football and basketball have the best recruiting scouts, they take all the athletes in highschool, and what young kid would rather be a boxer that nobody knows instead of a superstar who is on top of the world? Even guys like Mayweather and Pacquiao are just whispers in the wind in the sports world compared to guys like Kobe Bryant, Tom Brady, Lebron James, etc.
