Buy-Low and Sell-High: Goalies

March 23, 2022 Left Wing Lock Staff 0 Comments

Introduction

Welcome to Unsustainable - our weekly look at goalies performing at unsustainable levels. Below, you'll find a data table with an emphasis on save percentages. What we know, from years and years of data, is that it unlikely that a player can maintain a save percentage that deviates significantly from his career numbers.

The aim of this weekly article is to highlight players, that the data suggests, are playing at levels inconsistent with their actual talent.

Even-strength Save Percentage

We'll first look at the EVSV% of several goalies. To put this into context, it is rare for a starting goalie to maintain an EVSV% at or above the .940 level over the course of a season. How rare? At a rate of just under 1 goalie per season since the full-season lockout of 2004-2005. So what are the chances that the starting goalie on your fantasy hockey team is going to maintain that high, early-season EVSV%? Slim to none. Below, you'll find a list of starting goalies most likely to see a regression in their EVSV% in the future.

Player	CSV%	SA	EVSA	SV%	EVSV%
Charlie Lindgren	0.9134	118	103	0.9576	0.9515

Penalty Kill Save Percentage

Next, we want to examine the PKSV% of starting goalies. We know that PKSV% is largely driven by luck, so fantasy hockey managers should be aware of starting goalies with a SV% propped up by an unusually high PKSV% (for reference, the league average in recent seasons is .865). The ASV% column tells you what a goalie's SV% would look like if he were performing at the league average in PKSV%. Note that the list includes goalies with unusually high PKSV% values and goalies with unusually low PKSV% values.
