I don't want to watch the video, but skates are obviously a very dangerous part of hockey and this has been a safety topic before this particular injury occurred. I can't imagine there was intent to hurt a player with a skate. and Avery was one that spoke about this injury as far as intent goes. He is not one I would ever listen to about anything. One of my favorite players, Tyler Seguin, took a nasty skate laceration to his achilles in 2016. it ended his year and I think it ended stars' chances of winning a Stanley cup that year because back then he was an elite scorer. Ironically Tyler also got cut again by a skate last year. I would have always thought the puck or violent hits to the head were more dangerous (and maybe they are) but the skate injuries are really bad.
