Should the NFL adopt more aggressive rule changes to reduce head impacts, even if it changes how the game is played?
A study published Tuesday in The BMJ found that at least a quarter of former NFL players who died between 2016 and 2021 had chronic traumatic encephalopathy (CTE), the degenerative brain disease linked to repeated head impacts. Researchers from Mass General Brigham, Boston University and the Concussion & CTE Foundation examined 235 of the 878 former players who died in that window and whose brains were donated to the UNITE Brain Bank; 215 of them, or roughly 24.5%, had confirmed CTE. The study's authors say the real rate could run as high as 97.7%, though they describe that as a worst-case extrapolation.
By comparison, CTE affects less than 1% of the general population, according to the researchers. The study also found that 61.3% of the former players who had CTE met clinical criteria for dementia, with more advanced-stage disease tied to more frequent dementia diagnoses. The average age at death among the players studied was 66.5, meaning most had played decades before their deaths.
Dr. Daniel Daneshvar, the study's lead author, called the findings a wake-up call for the league and the scientific community. An NFL spokesperson said the league continuously strives to make the game of football safer, including by implementing strategies to reduce concussions and head impacts.
Arguments for:
The study's minimum estimate of one in four ex-players developing CTE is dramatically higher than the sub-1% rate in the general population, giving concrete data to justify further safety reforms.
Researchers found CTE was linked to dementia diagnosed while players were alive, meaning the disease showed measurable cognitive costs, not just a postmortem finding.
Team and union voices have called the findings a call to action, signaling some appetite inside football for further changes to protect players.
Arguments against:
The 235 studied brains all came from families who chose to donate, a group likely skewed toward those who noticed symptoms, so critics argue the true population-wide rate is probably lower than the extrapolated range suggests.
More aggressive limits on contact risk altering tackling, practice structure and other elements central to how the sport is coached and played.
The NFL points to existing concussion protocols and reduced-contact practice rules as evidence it's already addressing the risk, and argues further mandates should wait for more data.
