Yes. I don't think there's any single, explicit answer that will reduce and eliminate.... I think there are multiple pieces. I think zero tolerance plays a deterrent part, especially around deliberate contact to the head; around accidental contact, maybe per coaching, per understanding from the player. But yes, I do believe that you will see a reduction in the hate in which you go into a contact. That's an education piece.
We asked before about how we change a culture. It's going to take time to change a culture. We're not going to see an immediate change. I would say role models play a key part: what our international athletes, what our professional athletes do. If we see on TV something that is a zero tolerance then that's going to filter down to our young kids. So, yes, I do believe that a zero tolerance approach to contact to the head does reduce concussion-related injuries.
