Agreed. There’s simply not enough information to get much out of the position other than Goals Saved Above Expected.Analytics for goalies suck.
Analytics for hockey sucks.Analytics for goalies suck.

There are significant issues with the quality of the data being input (NHL public shot data is notoriously bad), and the context/lack of context a lot of this is used. Shot location is the basis for all of these conclusions.Why do so many people try to tear down analytics? I think they are fascinating.
TIL: Hellebuyck not a top 10 goalie
Makes perfect sense.
This is why I don't trust analytics, Demko is in a top 10 goalies list.
Stop it
6 of the Top 10 goalies by this measure are in the West.View attachment 401965 The top 10 goalies so far according to analytical data, thoughts?...... and I see I managed to remove Goalies from the thread title....

I always found this criticism of public analytics to be kinda strange to be honest. What should we use instead? Points? The eye test? Analytics are no where near perfect in hockey, but neither is any other method we use to form our opinions. It appears that analytics is held to a higher standard than the others for some reason.There are significant issues with the quality of the data being input (NHL public shot data is notoriously bad), and the context/lack of context a lot of this is used.

Problem? It does not factor in situation. The most obvious being pre-shot movement. What is the better scoring chance - Ovechkin taking a one-timer from the top of the circle from a cross ice pass, or Pat Maroon banging on a shot right in front of the goalie where the goalie is in position? [Public] analytics are going to say that the Maroon shot is more dangerous.
It's got an extra issue when applied to goaltenders. An xG as far as judging a skater does not equal an xG for a goaltender because it only factors in the shot location, but not the quality of the shot. A player flubs a shot and it dribbles in unscreened? That's not the same as judging it by it's shot location. Shot from the blueline with a double screen? Also not factored in.
I think private data (NHL teams and some contractors) is probably much better, and why it's better is because the data collection is largely better.

That being said hockey is kinda a shit show of randomness at the NHL level, and I’ve found it to be a lot more enjoyable watching this year by not focusing on any stats, advanced and standard.
