Jaroslav Spacek was the best player on the ice for the Canadiens last night in Boston. This is the conclusion of hockey’s newest method of statistically determining individual on-ice performance called the “Corsi Number”.
The late Ron Andrews designed the NHL’s plus/minus system of player ratings in the mid-1960’s when he was the NHL’s Publicity Director and Statistician. We’ve since moved into the computer age and it’s now possible to delve deeper into the numbers. Hence, the so-called Corsi Number, a system designed by current Buffalo goaltending coach Jim Corsi.
About The Corsi Number – Recognizing that the NHL’s plus/minus figures,shots on goal and goal totals tell only a partial story, Corsi took things four steps further. The Corsi Number is the shot differential while a player wis on the ice. This includes not just the team’s goals and shots on goal, but also shots that miss the net, and in some formulations, blocked shots while the player is on the ice. In other words, it’s the differential in the total number of shots directed at the net both offensively and defensively. The end result is a picture of how the team did territorially during the time that player was on-ice.
Spacek Leads Corsi’s vs. Boston– Spacek was on the ice for no goals for or against. During his 29 shifts, Spacek was on the ice when Tuukka Rask had to make 10 saves while Carey Price had to make 6 the differential was plus-4. The Canadiens missed 5 shots while Boston missed one-Differential of 4. Total plus-8. That’s the Fenwick number. Corsi added shot blocking. Five Canadiens shots were blocked to just two by the Canadiens. Another plus-3. So Spacek’s total Corsi Number was 11 – the Canadiens best on the night. To simplify it, while Spacek was on the ice there were 20 incidents in the Boston end (goals, saves, missed shots, blocked shots) to only 11 in the Canadiens end. Spacek’s partner Roman Hamrlik was plus 10. Mathieu Darche was plus-10 as well. On the bottom side Michael Cammalleri, who some thought worthy of a game star, was minus-3. Andrei Markov minus-2
