Top 20 Raw Corsi Ratings

In an effort to look at sabermetrics and hockey, I am beginning the look at Corsi Ratings from last season.  The idea behind Corsi Ratings is that they are to be similar to +/- ratings but with a much bigger sample size and hence better signal to noise.  A player’s Corsi is recorded in 5 on 5 play only (here at least) and is the sum of attempted shots (shots on goal, missed shots and blocked shots) for a team minus the attempted shots against while a player is on the ice.  It gives a very good measure of puck possession, as the team with the puck takes the majority of the shots.  Just like +/-, it is affected by many factors aside from the skill of an individual player.  A player on a good team will have a good Corsi.  A player on a bad team will have a worse Corsi.  A player who plays against weak competition will have a better Corsi than one who plays against strong competition.  A player who frequently starts shifts in his own zone will have a worse Corsi than one who frequently starts shifts in the offensive zone. 

Today we are looking at raw Corsi ratings.  Which players have the best Corsi ratings with no adjustments at all?  Later we will attempt to adjust them.

Here are the best 20 players by raw Corsi ratings in 2010/11:

Certain teams have several players on this list.  That shows the importance of playing on a good team to a raw Corsi rating.  Vancouver has Ryan Kesler, Christian Ehrhoff, Daniel and Henrik Sedin and Mason Raymond on this list.  Kesler leads the league.  His story is interesting and will be written about further in the future.  Last year it took adjustment to show Kesler had a good Corsi.  With his changed role with the Canucks in 2010/11, he led the league outright.

San Jose places Ryane Clowe, Logan Couture, Joe Pavelski and Jason Demers on this list.  Chicago has Jonathan Toews, Duncan Keith and Patrick Kane.  More than half (12 of 20) players come from three teams.  New Jersey places two players in Patrik Elias and Henrik Tallinder.  The other players are the only ones from their teams.  Alexander Steen of St Louis, Kris Letang of Pittsburgh, Brian Rafalski of Detroit, Dustin Byfuglien of Atlanta, Justin Williams of Los Angeles and Brian Gionta of Montreal are the only players from their respective teams.

This raw Corsi list needs a little bit of adjustment and interpretation to better understand why the players who appear on it are there and how much of it is the player’s own skill versus other factors such as the way they were used.  It shows the players whose teams most controlled puck possession when they were on the ice.  These player’s teams succeeded when they were on the ice in 2010/11.  With a little work, we can better isolate individual player’s contributions.
