A model that considers both shot quantity and quality in order to provide a metric for how many goals a team (or player) should have scored, given the quality of scoring chances generated, if the opposing goalie played at a league-average level. Expected goals accomplishes this by weighting each unblocked shot attempt by a variety of shot attributes, with heavier weightings applied to shot characteristics with a higher chance of leading to a goal. The shot characteristics considered by expected goals include shot type, distance from the net, shot angle, whether a shot was a rebound or generated off the rush, and game state.

Game Score is a catch-all statistic that quantifies the total value of a player’s productivity from a single game. Game Score incorporates all of the following stats in an attempt to quantify the overall performance of a player: goals, primary assists, secondary assists, shots on goal, blocked shots, penalty differential, faceoffs, 5v5 Corsi differential and 5v5 goal differential. There is also a goalie version of Game Score that considers goals against and saves.

Stands for Goals Above Replacement and is one popularized model for a catch-all statistic to evaluate hockey player performance. What GAR does at its core, is takes the wins above replacement stat (WAR), and converts it to goals above replacement, with the methodology being that scoring a goal is the ultimate goal of any play in hockey.

This is a cumulative stat that represents the number of goals allowed by a goaltender compared to the number of goals that would have been allowed by a league average goalie.

This is a rate version of GSAA, and tells us how many goals saved above average a goalie has per every 30 shots he has faced.

This is a comprehensive model that, similar to the catch-all statistics provided above, accounts for a variety of individual components that are each “optimally accounted for.” However, K Rating is a team-level statistic that attempts to gauge the overall quality of a team with one metric. Think of K Rating as the team-level version of WAR.

Goals plus primary assists. Another way to look at this is primary points are total points minus secondary assists.

The sum of a team’s shooting % and their save %, converted into whole numbers. PDO is considered a measurement of luck, and in theory, if a team has a high PDO, that means they are getting an abnormally high shooting or save % (or both), and in most cases over large sample sizes, this is unsustainable and you can expect it to eventually regress to the mean.

The correlation that a stat has to the future success of a team or player.

The primary assist is awarded to the player of the same team who last touched the puck before the goal scorer.

Goals plus primary assists. Another way to look at this is primary points are total points minus secondary assists.

The difference between a team's expected goal differential when a player is on and off the ice.

Score adjusted statistics are those that are weighted in accordance to the game score in order to account for the fact that at various game states (e.g. a team is winning/losing) teams will be playing differently.

The secondary assist goes to the player of the same team who touched the puck before the primary assister.

Teammate relative statistics (abbreviated Rel TM) go a step beyond team relative metrics and attempts to further isolate a player’s performance by benchmarking his numbers against all of his individual teammates, instead of against his entire team in aggregate. Teammate relative statistics accomplish this by combining principles used in calculating team relative statistics and WOWY analysis.

Stands for Wins Above Replacement (just like baseball) and is one popularized model for a catch-all statistic to evaluate hockey player performance. WAR is only a player-level statistic, and it aims to quantify the total value a player brings to the team by accounting for a myriad of individual components.

WOWY (With or Without You) analysis attempts to help us understand how specific players impact one another on the ice. In essence, WOWY analysis looks at pairs of players and examines how they perform together versus apart. The key difference between WOWY analysis and relative statistics is that WOWY analysis examines the impact that one specific player has on another, while relative statistics attempt to illuminate how the entire team does with a specific player on the ice compared to when he is off the ice.

Stands for Weighted Points About Replacement and is one popularized model for a catch-all statistic to evaluate hockey player performance. It follows a similar construct to WAR and GAR, albeit with slightly different components and weights to make it unique.
