Yeah I kinda was addressing the way the league is called now in a broader sense, not specifically the blue line stuff.
Allowing as much clutch and grab hockey as they are almost directly decreases scoring, highly skilled players are driving into the offensive zone and being held up constantly which prevents scoring chances that could lead to goals. People want to see goals, people want to see stars dominate, people want excitement.
That's one of the reasons the NFL is so successful, fantasy leagues are driven by stats and scoring. When big players score, fantasy leagues are sustained. People watch games because they are in fantasy leagues, ratings on TV generate insane revenue for football. The NFL knows all this and has made adjustments to the game to promote it.
