Jim McMahon and five other players are suing the NFL over concussions:

Six former players and one current player have sued the NFL in Philadelphia over the league's handling of concussion-related injuries, the first potential class-action lawsuit of its kind. 

The players accuse the league of training players to hit with their heads, failing to properly treat them for concussions and trying to conceal for decades any links between football and brain injuries. 

The plaintiffs include two-time Super Bowl champion Jim McMahon, who has said he played through five concussions but now frequently walks around "in a daze" and forgets why he entered a room.

I've seen a lot of reporting around improving helmet safety, but virtually nothing dealing with the central challenge put forth in Malcolm Gladwell's piece from a few years back--Is the game, itself, so dangerous that it can't actually be reformed? The NFL, obviously, has no interest in answering this question, nor do many of the current players.
