It’s important when using statistics to make arguments or try to sway public opinion that you are not above learning something new. For me, this includes the effect of zone starts on scoring, how Corsi correlates to winning, and why scoring chances are an important metric to track. Each one helps put a player’s performance into context to try and determine the true skill level of a hockey player– both past and present. This is why I don’t change my mind, but I do make new decisions based on new information.
Take Washington’s goalies for instance. At first, I felt Michal Neuvirth deserved the right to be the “number one,” and I wasn’t wrong. He had a wonderful November and performed admirably. Then Semyon Varlamov’s groin started to heal and showed that he was ready to reclaim the number one spot– especially in the context of how he performed in different game situations.
