Edit: Just realized this a link to EZ. I grabbed it unwittingly off of KK. If you're worried about viruses or STD's, I wouldn't click through. That said, I'm going to go get examined. An Interesting read. Helmet technology is getting better at preventing brain injuries, except concussions. If this is the case, I bet Mueller's latest concussion would have happened even if he'd been wearing his not yet fitted M11. With the game getting faster, if helmets aren't the answer, concussions may just be a part of the NHL. I don't see how you can regulate them out of the game. Research and tech to the rescue?
