From someone who leans on advanced stats so heavily in all of his arguments, this statement is extremely surprising.
I see you've omitted all possession-related metrics in favor of using gf %, which, like plus minus, has a high degree of error due to the relative scarcity of goal events.
Staal spends 20% more time out of his zone. That's not a slight difference, it's the Grand ****ing Canyon. It's the difference in zone time between Pyatt and Malkin. Over a 2 year span.
Furthermore, Sutter was
such a failure in the tough minutes Staal is used to that the Penguins had to stop using him as a shutdown player this season. All of Staal's former difficult minutes
went to 87.
Sutter's worse numbers came in easy minutes. Not easier minutes. Easy minutes. Of centers that have played for this team this season, the only one given a softer landing than Sutter was Vitale.
He had to be given easy minutes because he
failed miserably at playing the role Staal played here and in Carolina. Linemate argument doesn't cut it either. Cooke saw a 20% negative swing in his own possession numbers going from Staal to Sutter. Kennedy fell off a cliff as well.
It's nice that Sutter's had 8 good games in a row and another 10 decent ones before that (not sure why it took 2 years for this to happen, but whatever), but let's stop pretending that a guy who flunked out of his job as a shutdown center, during said flunking, was 90% as effective as the second or third best defensive forward in the conference--who also happens to have been twice as productive offensively in the same period of time.
