I wrote down some stuff about this, too. I also have a couple of points. I wrote down that also at the top of the league, there's....
For amateurs, you should stop games that have too many penalties or that have become too difficult for officials to safely manage. I, personally, have had experience with those games. Tempers flare, and it's not a safe environment. There should also be fewer games, allowing for more skill practices and more skating work. It makes for better skaters, and better skaters are safer skaters. Players should also have safety-specific training to keep them out of harm's way and make them aware of risky situations.
At the top level, I think that the NHL influences how a lot of kids play, like a couple of people mentioned earlier. We all want to live that dream of playing in the NHL. Ken Dryden, who was here a couple of days ago, wrote a book and has many ideas on how to slow the game down and still make it exciting to watch and play. I also think that NHL players should keep in mind that there are a lot of kids out there who look up to them as role models, and they should watch how they play.
