Quote: Famous "I didnt think head guards did anything for concussion though? I maybe be wrong though. I also heard that they may actually make things worse as they lull players into a false sense of security, again maybe wrong though.'"
You could well be right there; I've never really looked into it too much but I suppose no flexible material could fully protect against some of the hits that go in at the top level (plus I always find they block out a lot of noise, making communication harder). Still, even if it's only a minor improvement in safety, it's still a step in the right direction.
