The Stars could have their magic moment as soon as Thursday night. The New York Rangers will take a penalty, and the planets will align. A to-be-determined Star will take advantage of the chance and score … the club’s first power-play goal of the season at American Airlines Center. The Stars are the only NHL club without a power-play goal at home. To put that into perspective, consider that St. Louis has scored a league-high 13 goals in 12 home games. “We’re not satisfied as a group with the way our power play has been going,” captain Jamie Benn said. “There’s a lot more room for improvement.” The Stars have played a league-low seven home games and been “a little bit snake bit” on power-play chances, coach Lindy Ruff said Wednesday. The relevant item is the Stars are 0-for-24 on the power play at home. This is not a new problem for the Stars. In 2011-12, their last full season, the Stars had 28 home games without a power-play score. It marked the first time since 1996-97 that the Stars had 20-plus home games without a power-play goal. With six of the next nine games at home, the Stars must solve this peculiar problem as soon as possible or risk squandering an advantageous portion of the schedule. “It’s a small sample, but it’s something we’ve been working on,” center Tyler Seguin said. “We’re trying to find something that’s going to click, at home and on the road.” For Ruff, the 0-for at home is part of a bigger problem. On the road, the Stars are a middle-of-the-pack power play with eight goals in 46 opportunities. “I’m not going to sugarcoat this,” Ruff said. “Overall, we need to be better on special teams as a whole. We’ll continue to work at it. “The power play at home hasn’t found ways to put it in the back of the net. We need them to finish.” Center Tyler Seguin and Ruff suggested the power-play groups may be guilty of over-passing, particularly at home. There is a long-standing hockey theory that teams sometimes look for the overly flamboyant play at home. That is no way to run a power play. Most power-play goals come on second chances from close range. That means going inside, where nothing is pretty. The Stars have done well on their entry into the offensive zone on the power play, Ruff said. The breakdown starts with too many passes and not enough activity around the net. “Our success will come once we getting inside and the second-chance opportunities start going in,” Ruff said. Chaisson may be out: A day after Ruff stressed the need for depth, the Stars may have lost a forward for Thursday’s game. Forward Alex Chiasson had to be helped off the ice during practice after being hit in the face by a hurtling puck. “We’re concerned that he might have some damage,” Ruff said. “I’m hoping all is well with [Chiasson], but you have to be ready for the adverse effect of what happened.”
