After failing to score a point in the first three games of December, Sharks center Logan Couture has caught fire over the last two games. He’s scored four points since Thursday, three of which came in Saturday night’s blowout win over the Ottawa Senators. There’s reason to believe his streak will reach a third game in Sunday night’s tilt with the Minnesota Wild: Couture’s scored 66 points in 84 career games on the second night of a back-to-back. That includes six in four such games this season, according to STATS. San Jose has certainly needed that kind of form from Couture, who leads the team in goals (15) points (25), and game-winning goals (3). The 28-year-old has scored or assisted a third of the Sharks’ goals, putting a fifth of them in the back of the net himself. It’s fairly easy to imagine where the Sharks would be without Couture. An already-anemic offense, the league’s third-worst, would still be sinking amidst the rising tide lifting all boats that is the NHL’s scoring boom.
