The ‘CIRV’ Stat (Comeback Impact Ratio Value) and Distribution Ratios
Ezra took a look at the numbers for four team (Jets, Leafs, Oilers and Capitals)
At the beginning of last season, my father John Ginsburg (a Math Professor at the University of Winnipeg for 32 years, now retired) was discussing who he thought would have the most goals and points for the Winnipeg Jets in the upcoming season. He then began discussing whether or not a statistic existed that measured the impact a goal/assist/point had on a game.
For example. Evander Kane scored 30 goals and 27 assists last season but what do those 30 goals and 27 assists mean as far as having an impact on a game? The reason why this is so important is because when a player scores a goal is undeniably more important than the goal itself. For further proof, one must only look at what has happened recently with 40-year-old designated hitter Raul Ibanez of the New York Yankees. Ibanez has 19 homers this season, 10 of which have tied the game or put or his team in the lead. Now that’s impact.
Lets me first explain the CIRV Statistic and the other distribution ratios. A distribution value refers to the distribution of a player’s goals, assists and points based on the three different stages of a game: when your team is ahead, when your team is tied and when your team is behind. The CIRV or “Comback Impact Ratio Value” is specifically what percentage of a player’s points occur when his team was behind.
