The claim is not a new one, even if we don’t hear it very often.
When things aren’t going well for the Rangers and questions about advanced statistics make their way back to Alain Vigneault, he reminds everyone of it: he has his own internal metrics (sophisticated stats) that he uses to make decisions.
A few weeks ago Steve Zipay wrote a blurb based off Vigneault’s comments on the matter:
A popular stat such as Corsi, for instance, doesn’t measure speed or determination or chemistry. It measures possession: shots on goal, missed shots on goal, and shot attempts blocked toward the opposition’s net at even strength while a player is on the ice, minus the same shot attempts directed at your team’s net.
