Predicting the future is what using statistical models of hockey is all about. Statistics, or things that happen in a game that we count up, can also be used to more accurately describe past games than our faulty perceptions can do. This is why we add up the goals for and against, after all. But if the measurements and the calculations you subject them to and the uses to which you put them don’t predict anything, than you might as well just flip a coin when it’s time to talk future wins.
Predicting the future is what Corsi does well.
