So far, so good. Oliver Lauridsen made an impressive NHL debut on Saturday, helping the Flyers surprise the Boston Bruins, 3-1, and inch to within four points of eighth place in the East. The 6-foot-6, 220-pound Lauridsen was part of a makeshift defense that was used because of injuries to Braydon Coburn, Nick Grossmann and Andrej Meszaros. Of that trio, only Grossmann is expected to return in the regular season. If he performs like he did on Saturday, Lauridsen will remain in the lineup. Playing alongside Luke Schenn (team-high 23:42 of ice time), Lauridsen contributed three hits, three blocked shots, and numerous shrewd decisions in 17:12. “He’s got a good stick and he’s really smart with the puck,” captain Claude Giroux said. “I’ve never seen him play before, but he’s a really good player.” Lauridsen, 24, a stay-at-home defenseman, was recalled from the AHL Phantoms because of Coburn’s separated shoulder. “I was really stoked. It was a great feeling,” he said of the promotion. “It’s what you’ve been waiting for….This is what you work for your whole life, and it’s nice to get a shot in Philadelphia with the big show.” Lauridsen conceded it took him a while to feel comfortable. “Obviously I was a little nervous at the start,” he said. “It felt really good to get the first period out of the way, and then my instincts kind of took over after that.” Schenn had been paired with Kimmo Timonen most of the season, but coach Peter Laviolette broke up the duo Saturday.
