On Sunday, the NHL’s website published my long read on the place of analytics in hockey and why they are so critical. As you know if you read it, it contained a lot of material, and good for you if you managed to understand it all. It was the product of months of revising and editing, and in the end a complete section needed to be cut. I made the decision to cut that section – which focussed on evaluating defense – in order to add substance to the other sections, and because I didn’t think it entirely fit. Here is that section:
EVALUATING DEFENSE WITH ANALYTICS
Evaluating defense is an area in which analytical findings have helped to shape perception. Conventional analysis dictates that the best players at preventing goals do so through proper positioning, good stick-work, blocking shots and hitting the opposition. Those things can be important when the other team has the puck, of course, but they don’t paint a full picture of a player’s effectiveness at preventing goals.
