Readers of the blog know I put a lot of stock into numbers to help put context around which players are performing and which aren’t. Corsi is one of my favorites because it is a good proxy for territorial possession in a game. To get a player’s Corsi rating, simply add up all the goals, shots on goal, missed shots and blocked shots of that player- both for and against- when he is on the ice. If it is positive, that player helps create scoring chances, and if it is negative – well, the opposite happens. Or, simply go to Behind the Net, and let them do the work for you.
