A New York Times investigation finds that there may be flaws in the National Football Leagues conclusion that their Heads Up program has reduced concussions. After going through the detailed data of the study that the NFL relied on, the Times concludes that the program had little impact and that other changes in the Pop Warner program actually were the cause of the overall changes.
Rather than looking at Heads Up Football leagues in one category, the paper instead split them into two groups: those that did or did not also belong to Pop Warner Football, a division of youth leagues that has added its own rules to mitigate injuries. Pop Warner leagues have disallowed certain head-on blocking and tackling drills and drastically reduced full-contact practice time, measures that were not a part of U.S.A. Football’s program.
As it turned out, only leagues that adhered to Pop Warner’s rules saw a meaningful drop in concussions. Leagues that used Heads Up Football alone actually saw slightly higher concussion rates, although that uptick was not statistically significant. The previously reported drops were clearly driven by a league’s affiliation with Pop Warner, not Heads Up Football.
