Is the reason for the cucussions that the game has gotten so much faster? I think that is part of the reason. Players are bigger and faster. The rules changes to allow more open ice skating has put players at risk for blind side hits. The strict enforcement of no hits to the head will decrease the amount of head hunting. The medical precautions when a concussion is suspected will decrease the number of 2nd hits which can make it even worse. But is that enough?

Hockey players wear helmets that are inferior to even high school football helmets from 20 years ago. Why can't hockey take football's lead and develop and mandate better helmets for all players? Is it that hockey players do not want to look like aliens? Develop better helmets with more padding/suspension, paint them black and put the logo on the right side only. You'll fit right in.

I agree player safety should be priority #1, but the equipment companies have a role to play.
