Both Andersen and Reimer in the top 10, behind Campbell.

Gonna cycle through a bunch of the fringe types over the next little bit, I imagine.

Until Dermott gets back at least..Dahlstrom looks good on the Marlies. Stay at home guy. Glad to see Seney up

Sounds like the game Thursday vs the Flames is going to be postponed...

How can these guys still want to go to China for the olympics?

So is this chart good or bad?  Does it not mean that Campbell is playing way above his head and that he might not be able to sustain it?

Six players have been placed on Covid protocol.

No, it's good. Or rather, it's a reflection of how well he's played so far this year. The better goalies are going to save way more goals than average or "expected", which is what this reflects about how he's performed so far.

I'm probably arguing semantics here, but if he is making more saves than expected, doesn't that mean one of two things:
1.  He is playing over his head and making saves that he shouldn't.  Wouldn't that point to luck at some point, like PDO?
2.  If expected doesn't point to what is expected of him as a goalie, then would it not point to the Leafs defense being bad, and that he has to make more saves than what is expected?

There's descriptive results and predictive metrics. This one is, as Heroic Shrimp explained very well, the descriptive result, a couple steps more complex than a W-L record or Sv%. A high GSAx correlates strongly to Sv% and Ws though.

If you want a predictive measure, you'd have to compare this to his historical GSAx, but it will be a high variance estimate given his rather small sample playing on this team. Vasilevskiy is often near the top of these charts, for example. If his current year numbers are out of whack with his past performance, there's a significant element of luck involved (or playing through injury, etc.).

Goalie evaluation requires a good deal more input to develop a foundation of context to anchor results reliably. Public models will struggle with this because there just isn't enough data available in the NHL scoresheets for things like rebound control, screened shots, tipped shots, rush chances, and how all of those figures are skewed by the team playing in front of the goalie.

The term Expected here refers to an NHL average shooter vs NHL average goaltender (sampling all the shots from that spot in previous data and seeing how often it went in).
