Flashback to 2016 when it was divulged:
For the last 13 years, the N.F.L. has stood by the research, which, the papers stated, was based on a full accounting of all concussions diagnosed by team physicians from 1996 through 2001.
But confidential data obtained by The Times shows that more than 100 diagnosed concussions were omitted from the studies — including some severe injuries to stars like quarterbacks Steve Young and Troy Aikman. The committee then calculated the rates of concussions using the incomplete data, making them appear less frequent than they actually were.
After The Times asked the league about the missing diagnosed cases — more than 10 percent of the total — officials acknowledged that “the clubs were not required to submit their data and not every club did.” That should have been made clearer, the league said in a statement, adding that the missing cases were not part of an attempt “to alter or suppress the rate of concussions.”
Some retired players have likened the N.F.L.’s handling of its health crisis to that of the tobacco industry, which was notorious for using questionable science to play down the dangers of cigarettes.
Concussions can hardly be equated with smoking, which kills 1,300 people a day in the United States, and The Times has found no direct evidence that the league took its strategy from Big Tobacco. But records show a long relationship between two businesses with little in common beyond the health risks associated with their products.
