Yes. I agree 100% that the culture needs to change, but I believe Carter's first three concussions wouldn't have happened if he'd been wearing the correct helmet for his level. There were many opportunities for somebody to have figured that out. All it would take is a list and a trainer on every team, even for the little guys, to tell them what kind of approved helmet they need to be safe.
When Carter received the correct helmet, he never again received a concussion from a puck to the head.
