Don’t understand how this works well enough. That chart doesn’t seem to reflect reality for Lemieux. How are all his goals and his overall decent looking play not improving his “impact”?
It only looks at how many shots and where the shots are coming from (and other shot quality factors).
It ignores whether or not the shots actually go in.
The numbers would suggest that Lemieux has been lucky and that his current performance would unlikely repeat if he did the same games next year and got the same chances.
The Jets score on 13.3% of shots when he's on the ice, which ranks 5th highest of all players with at least 200 mins.
The Jets goalies have a 0.962 save percentage when he's on the ice, which also ranks 5th highest.
Overall, Lemieux ranks #1 in PDO (and Appleton #2). That lucky variance distribution doesn't just mean his goal totals are a bit of an illusion, but perception of performance is likely skewed.
Who knows... maybe Lemieux is even a better finisher than Laine, while simultaneously the greatest defensive player ever... but I doubt it.
