5v5 points are completely meaningless to me.
If Ovechkin scores 80 overall points and it includes 60 power play points, and if Matthews scores 78 overall points and it includes 20 power play points, all else being equal give me Ovechkin > Matthews, since 80 > 78. What's the difference? A point is a point.
Also - p/60. Again almost completely meaningless.
If Matthews scores 75 points playing 15 mins, and McDavid scores 100 points playing 20 mins. You can't say "p/60 is equal, so they're equal". No. Because the truth is - if Matthews gets bumped up to 20 mins a game, he won't score 100 points. Will he score more than 75? Sure. Maybe 81? 82? maybe 85? Similarly - if McDavid is bumped down to 15mins a game - he won't go down from 100 points to 75 points. Will he score less than 100? Sure, maybe. Maybe he ends up with 97, or 94. But not 75.
ps - just using names and made up number to explain my point - not meaning to pick on any players.
