‘Ristolainen, however, remains a bit of a conundrum to the analytics community. It’s not hard to find Web sites lambasting his play because his Corsi rating is hovering around 43 percent for the season, meaning opponents have 57 percent of all shot attempts when he’s on the ice. And he’s still carrying a minus-7 rating, although a good chunk of that came during his career-worst minus-5 outing last week against Philadelphia.’
