For modern fans of the Vancouver Canucks, following the team goes beyond goals and assists. Advanced statistics like Corsi and Fenwick have become essential tools for a deeper analysis of player and team performance. This glossary breaks down the key terms you’ll encounter in advanced metrics discussions, helping you understand what these numbers reveal about your favorite players and how they impact the game on the ice at Rogers Arena and beyond.
Corsi (CF)
Corsi is a puck possession metric that counts all shot attempts (shots on goal, missed shots, and blocked shots) for and against a team when a specific player is on the ice at 5-on-5. A player's individual Corsi For percentage (CF%) indicates their share of total shot attempts, with a percentage above 50% suggesting they are driving play in the right direction. For Canucks players like Quinn Hughes, a high CF% is often a hallmark of their ability to control the flow of the game.Fenwick (FF)
Fenwick is a close relative of Corsi but excludes blocked shots, counting only shots on goal and missed shots. The theory is that Fenwick (FF%) better measures "unblocked" shot attempts, which are considered higher-danger events. This stat can be particularly insightful when analyzing the offensive impact of forwards like Elias Pettersson, as it focuses on attempts that are more likely to become scoring chances.Corsi For Percentage (CF%)
Corsi For Percentage is the percentage of all shot attempts a team takes while a specific player is on the ice. Calculated as CF / (CF + CA), a CF% above 50% means the team is attempting more shots than the opposition with that player deployed. This is a foundational metric for evaluating a player's overall impact on puck possession, crucial for assessing the two-way game of a center like J.T. Miller.Fenwick For Percentage (FF%)
Fenwick For Percentage is the percentage of unblocked shot attempts (Fenwick) a team takes with a player on the ice. A high FF% suggests a player is not only driving possession but also generating attempts that are more difficult for defenders to get in front of. This stat is often used alongside CF% to get a clearer picture of offensive pressure.Relative Corsi (Rel CF%)
Relative Corsi measures a player's CF% relative to their team's CF% when they are not on the ice. A positive Rel CF% indicates the team's share of shot attempts improves when that player is on the bench. This metric helps isolate an individual's impact, showing if a player like Thatcher Demko is consistently facing tougher territorial matchups.Corsi Against (CA)
Corsi Against tallies all shot attempts (shots, misses, blocks) directed at a team's net while a specific player is on the ice. A low CA is a strong indicator of a player's defensive effectiveness and ability to suppress the opponent's offense. Defensemen and defensive-minded forwards aim to keep this number low.Expected Goals (xG)
Expected Goals is a statistical measure that assigns a probability to every unblocked shot attempt based on historical data of similar shots becoming goals. It factors in shot location, type, and other variables. A player with a high individual xG total, like Elias Pettersson, is consistently getting into high-danger scoring areas, even if they are in a temporary scoring slump.High-Danger Corsi (HDCF)
High-Danger Corsi counts shot attempts that originate from the most dangerous areas on the ice, typically the slot and the inner crease. For the Vancouver Canucks, generating a high HDCF is a key offensive strategy, as these attempts have the highest likelihood of beating the goaltender and resulting in a goal.PDO
PDO is the sum of a team's shooting percentage and save percentage at 5-on-5 while a specific player is on the ice. The league average tends to regress to 100.0 over time. A PDO significantly above 100 (e.g., 103) often indicates unsustainable luck, while one below 100 (e.g., 97) suggests unfortunate bounces. Analysts at sites like Canucks Army use this to predict potential statistical regression for players or line combinations.Zone Starts (Offensive Zone Start Percentage - OZS%)
This metric shows the percentage of a player's non-neutral zone faceoffs that begin in the offensive zone. A high OZS% indicates a player is being deployed strategically to generate offense, while a low OZS% means they are often tasked with defensive zone starts. Coach Rick Tocchet uses this data to manage matchups and player roles.Quality of Competition (QoC)
Quality of Competition is a metric that attempts to quantify the average skill level of opponents a player faces. A player with a high QoC rating is typically matched against the other team's top lines. This context is vital when evaluating the underlying numbers for a shutdown defender or a two-way forward.Quality of Teammates (QoT)
Conversely, Quality of Teammates measures the average skill level of a player's most frequent linemates. A player might have strong individual metrics due to consistently playing with other high-caliber players. This helps separate individual performance from the influence of linemates.Goals For Percentage (GF%)
Goals For Percentage is the percentage of total goals scored while a player is on the ice at 5-on-5. While Corsi and Fenwick measure process, GF% measures results. The ultimate goal for the Canucks is to have key players with a GF% well above 50%, meaning they are outscoring opponents during their shifts.On-Ice Shooting Percentage (On-Ice SH%)
This is the shooting percentage of a player's team while that player is on the ice at 5-on-5. An unusually high or low On-Ice SH% can heavily influence GF% and is a component of PDO. It can indicate shooting luck or the finishing skill of a player's linemates.On-Ice Save Percentage (On-Ice SV%)
This is the save percentage of a team's goaltender while a specific skater is on the ice at 5-on-5. A very high or low On-Ice SV% can skew a player's defensive results and is the other component of PDO. It reflects both goaltending performance and the quality of chances a skater allows.Corsi RelTM
Corsi Relative to Teammates is similar to Rel CF% but is calculated specifically against the player's own teammates. It provides a direct comparison of a player's possession impact within the context of their own team's performance, useful for internal evaluations by General Manager Patrik Allvin and his staff.Fenwick RelTM
Fenwick Relative to Teammates applies the same teammate-relative concept to Fenwick data. It shows how a player's share of unblocked shot attempts compares to the team average when they are off the ice, offering another layer of context for performance analysis.Individual Corsi For (iCF)
Individual Corsi For counts all shot attempts (shots, misses, blocks) taken by a specific player. It is a direct measure of a player's personal volume of shooting and offensive activity. A high iCF for a defenseman like Quinn Hughes indicates he is actively involved in driving offense from the blue line.Individual Expected Goals (ixG)
Individual Expected Goals totals the xG value of all unblocked shot attempts taken by a specific player. It estimates how many goals a player should have scored based on the quality of their chances. This is a more nuanced measure of offensive contribution than simple shot counts.Corsi On-The-Fly (COTF)
This refers to Corsi calculations that are tracked specifically for line changes made "on the fly" (not at a stoppage). It provides a more granular look at possession dynamics for specific line combinations during the fluid play of a game, relevant for in-game adjustments by the coaching staff.Score Effects
Score effects refer to the tendency of teams to play differently based on the game score (e.g., leading teams often sit back, trailing teams push aggressively). Advanced stats are often adjusted for score effects to provide a "score-adjusted" Corsi or Fenwick, which gives a truer picture of performance independent of game state.Zone Exits
A zone exit is a successful play to move the puck out of the defensive zone and into the neutral zone with control. Tracking zone exits is a micro-stat that highlights a defenseman's or forward's ability to transition from defense to offense, a critical skill in the modern National Hockey League.Zone Entries
A zone entry is a successful play to carry or pass the puck into the offensive zone with control, as opposed to "dumping it in." Players with high controlled entry rates are typically strong skaters and puck-handlers who drive offensive possession, a key trait for success in the NHL Pacific Division.Shot Suppression
Shot suppression refers to a team or player's ability to limit the number of shot attempts against. It is the defensive side of the Corsi equation. A team with strong shot suppression metrics is generally well-structured defensively, a key characteristic for any team with Stanley Cup Playoffs aspirations.In summary, Corsi, Fenwick, and their related metrics provide a powerful lens through which to evaluate the Vancouver Canucks. They move beyond the basic box score to measure puck possession, shot quality, and contextual performance. While they don't tell the whole story, understanding these terms enriches your analysis of how players like Hughes, Pettersson, and Demko truly impact the game, offering deeper insight into the team's strategy and its pursuit of success in a data-driven league.
