I get it. It might help.
To be honest I couldn't care less about my team playing McDavid at home every year, or Bedard, or whomever.
This might help hockey to a degree. It will dilute the skill level so players who really aren't NHL material will make it and allow for more goals, more skill plays as it's easier to pull on inferior opponents. Likely brings back some tougher players and could result in more animosity, which this game and sports in general is severely lacking.
At the same time the NHL will just push it so you play every team minimum twice and less games against "rivals", teams just adapt a more defensive play and now you have the dead puck era again and shit hockey.
You look at celebrities, or stars from other sports who like hockey and when asked why they're usually talking about the fights and speed.
Hopefully I'm dead wrong and there's some animosity that comes back, but not the Marty McSoreley type.
