The National Football League was on the clock.
With several of its marquee players retiring early after a cascade of frightening concussions, the league formed a committee in 1994 that would ultimately issue a succession of research papers playing down the danger of head injuries. Amid criticism of the committee’s work, physicians brought in later to continue the research said the papers had relied on faulty analysis.
Now, an investigation by The New York Times has found that the NFL’s concussion research was far more flawed than previously known.
