Today I return to my summertime sabermetrics and hockey series by looking at the top 20 players in 2013/14 by raw unadjusted Corsi ratings. This is the beginnings of an individualized ranking of puck possession ability. Corsi measures the difference between the attempted shots (shots on goal, missed shots and blocked shots) taken in 5 on 5 situations by a given team and their opponents when a given player is on the ice. It has been shown to correlate very well with puck possession on a team level. When looking it as an individual ranking there are several factors which must be removed. The most obvious is team effects. A good team is more likely to possess the puck than a bad team. Thus a player on a good team is more likely to have a good Corsi than a player on a bad team. In time I will correct for those and other effects.
Here are the top 20 players in the 2013/14 season by raw, unadjusted Corsi rankings:
|1||Anze Kopitar||Los Angeles||+507|
|2||Jake Muzzin||Los Angeles||+469|
|3||Justin Williams||Los Angeles||+426|
|6||Marc-Edouard Vlasic||San Jose||+418|
|7||Drew Doughty||Los Angeles||+413|
|8||Joe Thornton||San Jose||+404|
|12||Jaromir Jagr||New Jersey||+367|
|14||Travis Zajac||New Jersey||+330|
|15||Dwight King||Los Angeles||+322|
|18||Joe Pavelski||San Jose||+307|
|20||Brent Burns||San Jose||+299|
|20||Anton Stralman||NY Rangers||+299|
This list actually has 21 players due to a tie in 20th place. These 21 players represent seven teams in the NHL - Boston, Chicago, Los Angeles, New Jersey, San Jose, Ottawa and the NY Rangers. All teams have at least two players on the list except for Ottawa and the Rangers who have a player each near the bottom of the list. There are five players each from Chicago and Los Angeles. This leads the league. This clearly shows that team effects are significant in individual player raw Corsi rankings.
These players must be good players to have as good puck possession numbers as they have but the fact that this list is limited to so few teams is going to be corrected using team adjustments. First, I will write a post about Anze Kopitar and his league leading Corsi and what it means.
