relGF% 5v5 has some value, but the problem with plus minus is it includes short handed goals for and against, empty net situations, and 3 on 3. At 5v5, among forwards who’ve played significant games for the team, Pettersson is 4th in SA/60, 3rd in GA/60, 4th in xGA/60, and 5th in SF%, 5th in xGF% but only tied for 8th in GF% because the team hasn’t scored enough with him on the ice, which also shows there’s a lot of variance when only looking at goals over a 30ish game sample.
And then even relative numbers don’t take into account teammate and competition quality. For instance, Miller gets a ton more ice time with Hughes than Pettersson, which significantly affects Pettersson’s numbers since the rest of the Canucks D can’t move the puck. 57% of Miller’s ice time comes with Hughes on the ice, whereas only 43% of Pettersson’s 5v5 ice time comes with Hughes on the ice. He also typically plays the hardest minutes on the team with over 39% of his ice time coming against elite competition.
That’s why Pettersson’s GAR numbers and RAPM numbers that take teammates and completion into account are strong defensively.

It’s his offense that’s been bad this year.
Now, Stutzle’s numbers are even stronger this year while also scoring at a high rate. He’s made strides in his overall game and he’s clearly been much better this year. I don’t think the poster’s comment that by the end of the year Pettersson’s going to be better offensively and defensively and everyone’s going to hide is a likely outcome at this point. Stutzle’s on pace for just under 100 points this year and should probably beat his 90 from a couple years ago. Pettersson meanwhile hasn’t been himself for a long while now and whether it’s his apparent knee injury or issues with the team, we have no idea when and if he’s going to flip a switch. Still, focusing on plus minus, even against your own teammates, is a horrible way to judge players, especially if you’re just trying to judge defense.
