Hey Flames fans! Ever find yourself reading a deep-dive on Connor Zary's progress or a breakdown of Jonathan Huberdeau's playmaking and feel like you need a decoder ring for all the analytics terms? You’re not alone. The world of hockey stats has exploded, moving far beyond just goals and assists. For a team like the Calgary Flames, focused on building for the future, these metrics are crucial tools for evaluating talent, shaping systems under head coach Huska, and making decisions in GM Conroy's front office. This glossary will break down the key analytics terms you need to understand the modern game and how they relate to player development right here in the West.
Corsi (CF%)
A puck possession metric that counts all shot attempts (shots on goal, missed shots, and blocked shots) for and against a team when a player is on the ice. A Corsi For percentage (CF%) above 50% means that player’s team is controlling the shot attempt battle during their shifts. For a young player like Zary, a strong CF% suggests he’s helping drive play in the right direction, a key trait the Flames value.
Fenwick (FF%)
Similar to Corsi, but it excludes blocked shots, counting only shots on goal and missed shots. The idea is that Fenwick (FF%) measures "unblocked shot attempts" and can be a slightly cleaner indicator of possession and scoring chance generation. It’s particularly useful for evaluating offensive zone pressure.
Expected Goals (xG)
A statistical measure that assigns a probability to every unblocked shot attempt based on factors like shot location, type, and rebound status. It estimates how many goals a player or team should have scored given the quality of their chances. If Huberdeau has a high individual xG, it means he’s getting to high-danger areas, even if the puck isn’t going in yet.
Goals Above Replacement (GAR)
A catch-all metric that estimates a player’s total contribution, in goals, compared to a readily available replacement-level player (like a minor-leaguer). It combines offensive, defensive, and special teams impacts into one number. It’s a great tool for the league-wide comparisons of overall value.
Wins Above Replacement (WAR)
The cousin of GAR, this metric converts a player’s total contribution into an estimated number of wins they add to their team over a replacement player. It’s one of the most comprehensive single-number evaluations of a player’s worth.
PDO
The sum of a team’s shooting percentage and save percentage while a specific player is on the ice at 5-on-5. The National Hockey League average is always 100 (or 1.00). A PDO significantly above 100 suggests unsustainable luck, while one below indicates potential positive regression. It’s a key "reality check" stat.
Zone Starts (Offensive Zone Start Percentage - OZS%)
The percentage of a player’s non-neutral zone shifts that begin with an offensive zone faceoff. Players like Nazem Kadri might have a high OZS% as the coach puts them out to create offense, while defensive specialists get more defensive zone starts. Context is crucial when using this stat.
High-Danger Chances (HDCF)
Shots taken from the most dangerous areas on the ice, typically the slot and the inner crease. Tracking these for and against a player gives a clearer picture of true scoring threat quality, beyond just total shot volume.
Goals Saved Above Expected (GSAx)
An advanced goaltending metric that compares the number of goals a goalie actually allowed to the number of goals they were expected to allow based on the quality of shots faced. It isolates the goalie’s performance from their team’s defense. Jacob Markström’s GSAx is a critical measure of his true impact in the Saddledome crease.
Point Shares (PS)
A metric that attempts to divvy up team points in the standings among its players, estimating how many standings points each player is responsible for. It accounts for both offensive and defensive play.
Player Usage Chart
A visual graph that plots a player’s quality of competition (on one axis) against their zone start percentage (on the other), with a bubble representing their Corsi Rel (see below). It’s a fantastic snapshot of a player’s role and performance.
Corsi Relative (CF% Rel)
Measures a player’s on-ice Corsi percentage relative to their team’s Corsi percentage when they are off the ice. A positive number means the team’s shot share is better with that player on the ice. It helps identify players who drive play independently of their linemates.
Game Score
A daily metric that aggregates a player’s box score stats (goals, assists, shots, blocks, etc.) into a single number to measure their performance in a specific game. It’s a handy way to quantify "who had a good game last night."
Ice Time (ATOI)
Average Time On Ice. While simple, it’s a fundamental development metric. An increasing ATOI for a rookie is a direct signal of growing trust from the coaching staff, like Ryan Huska, in their ability to handle more responsibility.
Primary Points (P1)
The sum of a player’s goals and primary (first) assists. This focuses on direct involvement in scoring a goal and is often seen as a measure of direct offensive impact, separating playmakers who make the key pass.
On-Ice Shooting Percentage (oiSH%)
The shooting percentage of a player’s team while they are on the ice at 5-on-5. A very high oiSH% for a playmaker like Huberdeau might indicate his linemates are finishing chances at an elite rate, which can be insightful for line construction.
On-Ice Save Percentage (oiSV%)
The save percentage of a player’s team while they are on the ice at 5-on-5. A low oiSV% for a defenseman might point to bad luck or a need to reduce the quality of chances they allow in front of their goalie.
Rush Attempts
A tracked event counting offensive chances generated off the rush (with speed through the neutral zone). For a fast-paced team, tracking which players create rush chances is key to optimizing transition play.
Controlled Zone Entries/Exits
Measures a player’s success rate at carrying or passing the puck into the offensive zone (entry) or out of the defensive zone (exit) with control, as opposed to just dumping it in or out. This is a core skill for modern defensemen and puck-carrying forwards.
Scoring Chances For (SCF)
The raw count of scoring chances a player’s team generates while they are on the ice. This is a step more selective than Corsi, focusing on shots from dangerous areas. Monitoring this for developing players shows their offensive involvement.
Penalty Differential
The difference between penalties drawn and penalties taken. A positive differential is highly valuable, as it means a player is putting their team on the power play more than the penalty kill. It’s a measure of disciplined, effective play.
Quality of Teammates (TOI% QoT)
An estimate of the average quality of a player’s most frequent linemates, usually based on their Corsi impact. It helps contextualize a player’s results—succeeding with weaker teammates is a good sign for player development.
Quality of Competition (TOI% QoC)
An estimate of the average quality of opponents a player faces. Being deployed by head coach Huska against top lines in the Pacific Division every night is a tough assignment that will affect a player’s raw stats.
Individual Point Percentage (IPP)
The percentage of on-ice goals for a player’s team that they get a point on (goal or assist) at 5-on-5. A very high IPP (say, over 80%) can indicate a player is a primary driver of offense, while a very low one might suggest they are often a passenger on their line.
So, the next time you see a tweet about Kadri’s stellar expected goals or read an analysis of Markström’s goals saved above expected, you’ll be equipped to join the conversation. These aren’t just fancy numbers; they’re the lenses through which the Flames' management evaluates progress, identifies needs, and builds a contender. Understanding them gives you a deeper appreciation for the game and the business of hockey, from the draft board to the roar of the C of Red at the Dome.
