Scott Cullen: Using Shot Metrics to Spot Player Up/Down Trends
By Scott Cullen, special for DobberHockey – It is easy enough to look at past scoring rates for players and that can provide a reasonable idea about what a player might be able to produce in the future. But there is more information available to dig a little deeper and one of the ways to do that is to look at changes in shot and expected goal rates to see whether a player has been creating more or fewer opportunities and whether or not they are trending in the right direction.
Sometimes that manifests itself in goals and points but not always so those underlying numbers can provide deeper evidence of a player's results, evidence that may not always be reflected in goal or point totals for a single season. This is the foundation for using shots as a source for hockey analysis: they provide a larger sample of data which can lead to more sound analysis.
While Bjorkstrand obviously improved his own production, scoring as many points in 49 games as he did in 77 games the season before, the on-ice metrics all improved significantly so Bjorkstrand and his linemates (Gustav Nyquist and Pierre-Luc Dubois were most common, Nick Foligno and Boone Jenner next) generated notably more shot attempts, shots, and expected goals per 60 than Bjorkstrand had the season before when Alexander Wennberg was his most common linemate. Opportunity matters. Hey, speaking of opportunity…
