My issue is nobody is answering why so many players never get it, and not finding other activities that cause brain dysfunction. Dementia and Alzheimers in people who never have played sports is a greater concern. And given obesity and sedentary lifestyle is suspected to be a cause, getting more young people active by playing football might actually be a net benefit to society in the long run.

Instead of assuming stuff, go look at the research BU CTE Center has done, both in the papers I listed and the ones in their Significant Research Findings.  They look at all who get repetitive head injuries (RHI) in other sports (hockey, soccer, etc) and professions (military) (and, they've done experiments on mice subjected to RHI).  They look for other factors in the lives of the football players to see if they could be the reason for the frequency of the maladies (see the Adverse Childhood Experiences paper).  One paper I saw indicated one gene vs another was associated with more CTE issues (IIRC: DQM).

(They do take brain donations, but only voluntary donations.  You're not allowed to nominate people ;-).
