It's very interesting. It's a part of lots of discussions about this subject. You talk about the players becoming more aware, and then it's “Yes, but the players want to play.” Then you want the coaches to be more aware, and you get out the cheat sheet that tells them to ask this question, and it's “Well, yes, but it's hard to get those out to everybody because most games are fairly informal” and this and that.
It's the same in terms of the doctors. You get this awareness out to them, but then you're into these moments of, "Is he okay? Is she okay, or is she not? She's almost okay", and you get into all that. You can do a lot better in each of those areas, but you're always going to have a “yes, but” in it. You're never going to get 16-year-old, 18-year-old or 25-year-old players who are going to say, with any great frequency, “I'm done. I know I can't continue", and doctors and coaches and all the rest of it....
That's why prevention matters so much. All of those other things offer partial answers, but they have answers you can drive a freight train through. The key to it all is in terms of doing the best you can to avoid the circumstance where the player is put into that situation, where the coach, the doctor, the trainer, the parent, the on-ice official or on-field official is put into that position, because we're going to fall short. We're going to fall shorter than we need to fall.
That's why we need to acknowledge that. Always try to do better that way, but don't assume that it's going to end up being your best answer. The best answer is still going to be in how we play and in the sports decision-makers.
