dumb rhetoric. boxing is just a game too, how come boxers aint beatin their families and murdering themselves ? and they take beatings just as bad. you are stretching cause and effect trying to match them together.
Well some boxers do, first of all. And I guess you don't realize that CTE is way more prevalent in football players than boxers, or athletes of any other sport for that matter. The VA/Boston U study showed that 96% of the former football players' brains they studied had CTE.
That aside, football players tend to show different symptoms because of the type of impacts they get. CTE is broad disease with different subtypes and symptoms. Boxers usually get injuries to the midbrain and cerebellum that leads to them being "punch drunk"...wobbly, messed up speech, Parkinson's, etc. whereas the acceleration/deceleration impacts football players get tend to result in mood disorders as well. That's why you see so many former football players engaging in erratic behavior dangerous to themselves and others--like Belcher blowing his brains out in front of the team, Strzelzyck speeding the wrong way on the interstate trying to kill himself, Seau driving his jeep off a cliff then later shooting himself, etc.
What was the point of bringing up boxers as a point of comparison anyway? Are you REALLY trying to deny the medically-proven causative link between CTE and aggression, impulsivity, dementia, etc. and just trying to blame it on personalities of people who play a violent sport?

You sound like someone who does PR for the tobacco or fossil fuel industry.
