Now that the Golden Knights have players, and will soon begin playing actual games and accruing statistics, we felt like now was a good time to learn the roster, by dumbing down different advanced statistics in the NHL.
Everyone understands goals, assists, points, penalty minutes, and time on ice, but for many hockey fans words like Corsi, Fenwick, PDO, and zone starts send off the instant “too much info, ignore and move on” signal. Since the Golden Knights are probably going to be bad, and the standard stats are likely to all have asterisks next to them with people saying “well someone has to score the goals,” we think it’s best if we use the downtime of July and August to take the stigma away from advanced stats, and get a feel for who the Golden Knights actual have on the roster.
Up first, Corsi and Corsi For Percentage.
Corsi is a statistic that measures the true number of shots a player takes during a game. It was created by an Edmonton Oilers blogger when he heard a GM mention the term “shot differential” but not have concrete numbers to back it up. So, like any good Internet user, he put in the research, came up with the numbers, and created a stat that’s now widely used in the NHL. So what is it exactly?
Corsi = Shots on Goal + Missed Shots + Blocked Shots Against
It’s fairly simple, it’s just all shot attempts. Corsi can be measured for a team or for an individual. For a team, it’s simply all shot attempts. For an individual, it’s all shot attempts by the team while that player is on the ice. So, for every shot, the team gets +1 on their Corsi rating, and five players get +1 on their individual Corsi rating.
Obviously that stat means nothing if not put in context with what the other team is doing. So, each player has a “Corsi For” and a “Corsi Against” rating. Corsi Against is simply a Corsi rating for the other team while a player is on the ice.
