Luke Kuechly has become the poster child of the concussion problem in the NFL.
The problem itself is not new; concussions in this sport have been an issue for decades. But there are more tentacles than ever, and Kuechly seems to be at the intersection of all of them. There’s the problem with identifying exactly what a concussion is. There’s the problem of understanding the “concussion protocol,” a term barely comprehended by the sport’s fans and only nominally more so by its media. There’s the issue of figuring out how many concussions Kuechly, 26, has really had in three NFL seasons.
