So a shoulder to a guy's head is clean? I'm not a hockey nut, but that just seems counter intuitive to me based on all the emphasis on concussions. Can you explain? Shoulder was main point of contact, not the head. He did end up getting him in the head. But his balance was off. I'd have to see it more but it's really hard to hit a guy with his head down without at some point hitting his head. But that's a check you have to make.
