That's a great question. No would be the answer. From our understanding, there's not a lot of evidence to suggest that the wearing of equipment can reduce the number of concussion-related injuries.
Two areas we believe very strongly can reduce concussion-related injuries are changing the laws of the game, for example, tackle height—zero tolerance—and also a cultural change. To look at equipment alone, we find that people will manipulate equipment and use it more as a weapon, potentially. Equipment in isolation, from our understanding, hasn't reduced the number of concussion-related injuries, but we do see education and influencing that culture as two key areas to reducing concussion-related injuries.
We are seeing an increase in the number of organizations and companies that are selling the answer to concussions as various different garments or helmets and so on. We just don't see the evidence there at this point. Whether or not that evolves in the future, at this point there's no requirement for a rugby player to be wearing a piece of equipment that would reduce the likelihood of a concussion-related injury.
