That's a terrific question.
I've seen a variety of changes. First, the medicine and knowledge about injuries, particularly concussions, is vastly different now from when I first took over. People didn't have the same knowledge. Concussions didn't get the same level of attention.
It's one of the reasons I decided in 1997 that we would be the first sports league to create a working study group of players of the league, trainers and doctors, to try to get everybody focused together to make sure that what we were doing on a unified basis would maximize the amount of knowledge that we could have and share within the NHL, and to make sure there was uniformity of treatment. Therefore, our ability to understand concussions and treat them is much better. That has been transferred to the players, as we've discussed, with education. What has also happened, for a variety of other reasons, is that there is more emphasis now in the game on skill, so you see far fewer teams that have hardly any players who are really not skilled hockey players and have other skills that were separate and apart from the game: fighters.
At the end of the day, what we're seeing is a healthier game, players more focused on player safety, and a game that is more entertaining and more competitive because the players are more skilful.
