The Detroit Red Wings find themselves at the bottom of the conference standings due to a fundamental flaw: They can’t score.When they finished with the worst record in the NHL last season, they averaged a league-low 2.0 goals per game.Through 21 games this season, they’re averaging a league-worst 1.86 goals per game. Detroit comes into its home game against Nashville on Thursday frustrated and baffled by its inability to generate production. The Red Wings were shut out by the Predators 2-0 on Tuesday.”You want to score and have the puck on your stick to make plays,” team captain Dylan Larkin said. “We’ve played good defense and we’ve had great goaltending. But to win games you have to score goals and we didn’t (Tuesday). It’s frustrating, but you have to shoot pucks, and we have to find a way to get the power play going. Everyone wants to score goals; we have to score goals.”The Red Wings have been shut out three times and scored a single goal in five other games. Their punchless power play has been a particularly vexing issue. They haven’t scored a man-advantage goal in 13 consecutive games and have just four power play goals all season.Nashville had nine more shots on goal (33-24) than the Red Wings.”We were fine structurally. We were fine how we played, but our individual players’ execution and battle level wasn’t good enough,” coach Jeff Blashill said. “We needed to execute better. The battle level was fine, but if we’re not close to 100-percent range, we’re not putting ourselves in position to win hockey games. We tried to make plays that weren’t there, and that bogged us down.”The Red Wings will be wrapping up a six-game homestand. They’re 1-3-1 since returning from a six-game road trip.Detroit hasn’t scored more than two goals in its last five games.
