Corsi Against At Even Strength Calculator

The formula for calculating Corsi Against At Even Strength per 60 minutes is: ((Shots Against + Missed Shots Against + Blocked Shot Attempts By Team) / Time on Ice in minutes) * 60. This formula provides the rate of shot attempts against per 60 minutes of even-strength play.

Corsi Against At Even Strength is used as a proxy for defensive performance and the ability to suppress offensive opportunities. The theory is that a team or player with a lower Corsi Against is better at preventing the opponent from controlling the puck and creating scoring chances. It's considered more predictive of future defensive success than traditional stats like goals against. The "At Even Strength" qualifier is important because it focuses on 5-on-5 play, which is the most common game state and generally considered the best indicator of true team strength.

This stat is crucial for understanding a player's or team's ability to suppress offense and control play defensively. Teams with low Corsi Against numbers tend to be more successful over time, as they're consistently limiting their opponents' offensive opportunities. For individual players, a low Corsi Against can indicate strong defensive contributions, even if those aren't always reflected in traditional counting stats like plus/minus.

Corsi Against, like Corsi For, was developed as part of the Corsi statistic named after Jim Corsi. It has been widely used in hockey analytics since the mid-2000s as a measure of defensive performance and ability to suppress shot attempts.

As analytics have become more prevalent in hockey, Corsi Against has become one of the most widely cited advanced defensive statistics. It's part of a movement towards understanding hockey through shot attempts and puck possession, rather than just goals and assists.

While useful, Corsi Against doesn't account for the quality of shot attempts faced, offensive zone starts, or the score state of the game. It also doesn't differentiate between a shot on goal and a blocked shot, which might have different levels of danger.

If a player is on ice for 500 shots against, 300 missed shots against, 200 blocked shot attempts by their team, in 1000 minutes of ice time, their Corsi Against At Even Strength per 60 would be calculated as follows: ((500 + 300 + 200) / (1000 / 60)) * 60 = 60 CA/60.

Teams like the Los Angeles Kings during their Stanley Cup runs in the early 2010s were known for their low Corsi Against numbers. Players like Patrice Bergeron of the Boston Bruins have consistently posted excellent (low) Corsi Against rates throughout their careers, contributing to their reputation as elite two-way players.
