      They are indeed. Just sent you an email with the raw data from ’22.

    Just wondering the methodology behind the values for the EGA table. As someone who is trying to get a better understanding of analytics, I would how to see how this compares to the EPA/xG models that football and soccer are using. Thanks!

      Basically, I count up how many times each play type occurs (call this TOT). Then I count up the number of times that the team-in-question scored within the next 60 seconds of play (call this myGoals). I also count up the number of times that the other team scored within the next 60 seconds (call this theirGoals). To get the expected-goals value for each type of event, the formula is (myGoals-theirGoals)/TOT.

      I suspect it’s fairly similar to EPA in football. I use a similar EGA/shot taken to come up with a shooting efficiency number for individual players; I believe quarterbacks are measured in a similar way with EPA/pass attempt.
