In hockey, Corsi is an advanced hockey statistic that calculates as follows:
Corsi = (Shorts on Target For + Missed Shots + Blocked Shots Against) – (Shots on Target Against + Missed Shots Against + Blocked Shots For)
All stats are taken from even strength, 5 on 5 play.
A “Blocked shot for” is considered to be a shot that is blocked by the team while they are in their defensive zone (and a “blocked shot against” is a blocked shot that was recorded by the other team while in their defensive zone).
If a team has the following stats:
For – Shots: 1,091 – Missed Shots: 417 – Blocked Shots: 182
Against – Shots: 918 – Missed Shots: 422 – Blocked Shots: 111
Their Corsi would calculated as:
Corsi = (1,091 + 417 + 111) – (918 + 422 + 182)
Corsi = 1619 – 1522
Corsi = 97
This team’s Corsi would be 97.
Cosri is an advanced statistic used in hockey that compares the total number of offensive and defensive “actions.”
What counts as a “Shot for” or “Shot against”?
In hockey, a “shot for” is a shot attempt that is either stopped by the goaltender or goes in the net.
A “shot against” is the opposite.
What counts as a “Missed shot for” or “Missed shot against”?
A “missed shot” is when a team shoots the puck towards the net, and it does not go in the net and is not stopped by the goaltender. A shot that is made and hits the net post or crossbar (and does not go in the net) is considered a “missed shot.”
What is “Blocked shot for” and “Blocked shot against”?
A “blocked shot for” is recorded when a team’s player that is not the goalie blocks a shot that was made against their net (in their defensive zone).
A “blocked shot against” is recorded when a player makes a shot towards the other team’s net and the shot is blocked (by a player who is not the other team’s goalie).
It should be noted that a “blocked shot for” is a defensive action, while a “blocked shot against” is an offensive action.
