According to the NFL’s own data, the league just went from a season in which there were most concussions recorded than ever before in 2017 to among the lowest. There were nearly 300 concussions diagnosed over the course of the 2017 season, including the preseason and the playoffs, but that was down to 218 last year, which is a lower figure than it has been for at least the past several years.
NFL Commissioner Roger Goodell lauded the improvement, which he probably should after the game came under heavy fire for the figures from the previous season, with the league’s chief medical officer even calling it “a call to action”, and the NFLPA expressed similar concerns.
