The NFL reported that concussions in the league decreased by 11% from 2015 to 2016. There were 244 concussions in 2016 compared to 275 in 2015. That's the good news. The bad news?
So even with a step forward in 2016 the year was still a negative compared to where the concussions were in 2014, and even in 2013 and 2012. In the three year period from 2012-2014 concussions dipped each season with 2015 bringing the big spike in the condition (+31% from 2014 to 2015).
The other argument about the data released is that is the number of reported concussions in the NFL. Everyone knows there has been some sketchy situation where players re-entered games after being cleared on the sidelines or locker room even though some hits those players took looked much, much worse than those of players who exited and potentially missed the following week as well. Perfect example came in the Wild Card round of the playoffs this season when Matt Moore of the Miami Dolphins got absolutely blasted by the Pittsburgh Steelers Bud Dupree ...
Moore was never taken to the locker room for further evaluation and recently the Dolphins were notified by the NFL that they did NOT follow concussion protocol:
So on the surface the numbers the NFL released look better than last year, but are they really? In the words of Tootsie Pops - The world may never know.
