I think like the article says, the way you reduce the pileup around the goalie is to
make it possible to score from places other than the pileup around the goalie.Just as the viability of 3-point shooters opened up the floor in the NBA, making it viable to score from the blue line in the NHL would open the ice as well.
When I was a kid in the 80s players would score from the blue line all of the time.
They were still relatively low percentage shots but a guy could absolutely score with a slapper from the blue line. Enough that you had to respect the threat. Not unheard of for a d-man to score 20 or 30 in a year.
As a fan that was fun too! Not as fun as a magical "sexy" Gretzky goal. But you could hear the anticipation in the building when the puck went back to some guy who had a cannon from the blue line. Al Iafrate, etc.
Today, if a defensemen actually scored from the blue line, the team would probably immediately release the goalie and fire the goaltending coach lol. Only reason to shoot from long range is so you can get the puck into the scrum in the slot and hope some something happens from there.
