Brock has certainly been impressive, a much smoother transition than I expected. It's great to see his hard work paying off, you can tell he made a mission out of improving his skating and first step over the summer. Kid has got great character - awesome to see another young American forward seamlessly make the jump.
All that said, I'm not sure if I'm ready to adjust my expected value for Boeser's production level. Yes, he's been producing, but he's way over performing based on expected goals. Let's dig a bit deeper.
He's got an impressive 8g 12p at 5v5 and 3g and 9p on the PP.
At 5v5 he's been on the ice for 14 GF, but his 5v5 xGF is only 7.3. He's got 12p on those 14 goals, which means he should probably have closer to ~6 5v5 points.
Extended to all situations, he's been on the ice for 23 Vancouver goals and has a whopping 21 points! What's more is that the team's xGF over that stretch was only ~14.5.
Two things stick out to me:
1) Vancouver's GF output at 5v5 while Boeser is on the ice is due for significant regression, and probably a bit of a slow up on the PP as well.
2) Boeser's point share on these goals is also due for regression, as it's far from likely that he'll continue to get a point on 91-92% of Vancouver goals scored while he's on the ice.
The combination of the two above factors will likely result in a pretty significant fall off for Boeser as the season continues. Based on averages, he should probably have about ~5-7 goals ~11-14 points right now, with half of them coming on the PP. That's still great production, but it's also well before opponents have begun game planning around him and goaltenders have adjusted to his shot.
None of that is meant to discredit Brock, just to shed light on how early production can be misleading, especially for rookies. I previously predicted he'd have 18 goals and 35-40 points - with his hot start thus far I predict he'll end up with 24g 49p if he plays the rest of the season.
I would challenge the usefulness of using xGF when evaluating elite high percentage shooters, which I absolutely believe he is. Have you seen his shot? It's unbelievable.
I'm not saying Boeser is Stamkos, but here are Stamkos's GF and xGF numbers for the last 7 years:

[TR][TD]2011-2012[/TD][TD]50.78[/TD][TD]80[/TD][/TR][/TBODY][/TABLE]
He's consistently batting ~40% higher GF than xGF over his entire career, which I'm sure in large part is due to his career 17% shooting percentage.
I wouldn't be shocked if Brock's shot settled in at a career number of somewhere around 15% and he routinely puts up significantly better GF numbers than xGF would predict, just like Stamkos - even if I don't foresee any 97p or 60g seasons like Stamkos put up.
Now, I do think he'll probably see some regression in xGF and some regression in his point share of goals scored while he's on the ice, but I think it's absurd to suggest that he should have only ~11-14 points right now.
