With many new statistics now on NHL.com after the League announced a partnership with enterprise software company SAP, the following is a primer on how some of them came into existence, what they mean, how they're applied, and why they're important.
SHOT ATTEMPTS (Corsi)
Puck possession has always been important in hockey, but analysts have proven how valuable it can be. Shot attempts are the best proxy for understanding and quantifying puck possession.
The idea for quantifying puck possession through shot attempts originally came from Tim Barnes, who posted his work online under the pseudonym Vic Ferrari. Barnes, who now works for the Washington Capitals, coined the term "Corsi," naming the stat after Buffalo Sabres goaltending coach Jim Corsi.
A shot attempt is counted any time a player tries to shoot the puck. They are counted as a shot on goal, blocked shot or missed shot. By adding those three types of a shot together, you have the number of shot attempts.
