Actually, ironically, I've been part of a joint concussion working group with the NHL and the NHL Players' Association. I represent the players, obviously, and I've been on that committee for approximately the last five years.
The program has been around since 1997. As for what we do, we look at the mechanism of the injury, the recovery times, and the return-to-play protocols. It's obviously very important to us as an association to make sure that the well-being of our players is taken care of. It's an ongoing challenge, if you will.
On rule 48, two years ago we changed the rule to try to make the game safer. You acquire all this information. You acquire how these injuries happen, and you try to figure out how you keep the integrity of the game and try to make it safer.
I don't know if I've answered your question.
