Decided to take another look at Pettersson’s scoring woes by the numbers. He’s got 30 points in 42 games this season, but if he were scoring at a 90-100 point pace he should have around 45-50, meaning he’s about 15-20 points behind where you’d hope he’d be. Of that, you’d expect about 6-7 more even strength goals, 4-5 more even strength assists, and 5-6 more PP assists.
Of that:
- Pettersson’s on-ice xGF is down about 5 xGF compared to his last three seasons. Since his xGF% is unchanged, it’s been offset by allowing fewer opportunities against. That is likely a system / conservative play issue, and has likely cost him 3-4 points this season, consistent with the drop off in assists.
- Pettersson’s on-ice and individual SH% are way down. For his on-ice SH%, if he were at his average rate the last few seasons he’d have 5 more assists. If his SH% were at his career average he’d have 2 more goals. Often percentages can be an indicator of bad luck, but Pettersson has always been a huge positive outlier for so long that it could also be a skill/play/system/linemate issue. For his assists at least, it is mostly his second assists that are down, which suggests it is more likely not a skill issue but it’s not strong one way or another.
- Pettersson is about 2 individual xGF behind where he would otherwise be, which is also contributing to his reduced goal scoring. Notably, he’s right on track with the last three seasons in terms of generating high danger chances for himself. This is basically directly tied to him taking fewer low and medium danger chances, which seems reasonable to attribute to being a system-related effect.
- As I noted in the last thread, Pettersson is basically in line with his career norms for PPG. But his assists are way down, about 5-6 behind where he should be. Notably his first assists are only 1 behind where his pace should be, but he’s 4 behind on secondary assists. Pettersson looks pretty weak as a primary playmaker on the PP and looks like he is being hurt by Miller’s decline in PP productivity.
On the whole, if Pettersson had 18 more points he’d be on pace for 94 points. Of that, about a third of the difference compared to his current pace looks to pretty clearly be related to the team’s system / playing low event hockey. That knocks off about 10-12 points from Pettersson’s full season projection.
Another third is connected to his playmaking on the PP. Pettersson has never put up huge assist numbers there so it may just be a limitation in his game, and it may not rebound without more help.
The final third is his percentages caving in. That seems to me to be the mushy middle where the question is how much is this a skill / play issue versus bad luck/system/teammates. The fact that the biggest decline is in his secondary assists suggests that something other than skill / play is at least contributing.
