We know there's a concussion problem. We do know that, and we do know what's happening to players who are wearing helmets. The question is, why is it happening, and is there a way in which the helmet can mitigate against these things?
My own personal approach to this is that there are two types of concussions: There are those that are unwarranted and those that are accidental. The unwarranted ones are intentional, really, caused when one player strikes another about the head. The accidental ones are when the youngsters fall and strike the ice or the boards with their heads unintentionally.
