New study finds at least 24.5 percent of NFL players who died from 2016 to 2021 had CTE

A surprise emerges as outlets differ on the exact prevalence—NBC Sports reports a precise 24.5 % while the BBC, CBS News and others round the figure to one in four. The underlying study, analyzing NFL players who died between 2016 and 2021, found that at least that share had chronic traumatic encephalopathy (CTE). NBC News framed the result as an alarming public‑health finding, while The New York Times ran a piece urging parents to consider ways to lower risk for young athletes.

ESPN highlighted that at least a quarter of former players could develop CTE, and the BBC headline echoed the one‑in‑four statistic as evidence of brain disease among ex‑players. CBS News reiterated the same proportion, and NBC Sports emphasized the 24.5 % number, reinforcing the study’s central claim across the coverage. The slight variation in percentages constitutes the only notable contradiction; no outlet presented data that diverges from the study’s baseline finding.

All reports converge on the conclusion that CTE affected a sizable portion of the deceased cohort. As the story circulates, attention is now directed toward how the NFL, medical researchers, and youth leagues will incorporate the evidence into safety protocols and future investigations.
