Now the serious season begins. The news of the day is there wasn’t much as the Shark began preparing for their first-round match-up with the Vancouver Canucks. Marty Havlat was back on a line with Patrick Marleau and Logan Couture after missing one game, and Scott Gomez was centering Andrew Desjardins and Adam Burish. Jason Demers didn’t skate because of his lower body injury and Todd McLellan ruled him out of the Game 1 lineup Wednesday night. The coach said Demers potentially could be ready later in the series, but he didn’t provide any specific target for his return. McLellan also didn’t commit one way or the other when it came to using veteran Scott Hannan or rookie Matt Tennyson, but he did spell out the choices pretty clearly. “We have Tennyson, who we think is a puck-mover and we have Scotty Hannan who has a lot of experience and he’s a heavy, physical D-man,” the coach said. “We have options there for Game 1 and maybe by Game 2 we have two puck-movers and one heavier guy if JD is ready to go. We’ll make some decisions over the next day or two and go from there.” Prevailing wisdom would have Hannan, with his 82 games of playoff experience, the edge. Not necessarily, said McLellan, who noted that veteran Chris Chelios didn’t necessarily play in every post-season game late in his Detroit career. “I think we look at our lineup and we make decisions on what we think can win that night. It’s nice to have experience,” he added, but “it can work for you and it can work against you and you don’t even have to listen to that old theory if you don’t want to.”
