The NHL hasn't adopted to the times either. There's next to no promotion of the league's superstars in the US and they haven't adjusted the rules enough for more free flowing play. There's still clutching, grabbing and constant cheap shots. The average score (3 goals a game) is the same now as when the Devils ruined the league with the trap zone 25 years ago.
The heyday of the league was the 80s when there was about 4 goals per game. The league should want their superstars like MacKinnon, McDavid, Draisaitl, etc. pushing 150+ points again. That is exciting.
Some of it's coaching because just about everyone is so conservative. It would be a lot more fun if every team in the league was always pushing the pace like Vegas.
