The story line needs to be told, and the NFL needs to listen ...
I'll preface this by saying that I have not seen it yet..
What exactly about the story needs to be told that we don't already know? Concussions are a huge problem in football. And all of sports. Particularly soccer, which does not get as much attention.
And we all already know some of the issues that ex-players are going through.
I think the NFL obviously knows all of this. Thus all of the rule changes to help prevent the most damaging type of hits.
Unless you stop playing the sport altogether, the problem will never completely go away.
So I'm not sure what else needs to be told. And how much more the NFL can do to make it safer. It's football. It's dangerous.
The players know the risks. Risk obviously is not great enough to most of these players to bi-pass the rewards of huge paychecks.
