Juuse Saros made 14 saves on 18 shots before being replaced at the start of the second period by Kevin Lankinen, who made 18 saves. Cole Smith and Tommy Novak scored for the Predators (27-25-2), who have lost five of their past six (1-4-1).
“Just a terrible game by us,” Nashville defenseman Ryan McDonagh said. “No other way to sugarcoat it. Weren’t ready to play. Lost every battle. Just gave them free offense and hung our goalie out to dry. That’s the worst part is leaving our goalies out to dry like that.”
Steel gave the Stars a 1-0 lead 35 seconds into the game on a shot that went through the legs of Predators defenseman Luke Schenn.
Duchene made it 2-0 at 4:27, taking a cross-ice pass from Mason Marchment on a 2-on-1.
“You never think you’re going to score nine, but we’re a really good offensive team,” Duchene said. “I think we’ve made some adjustments lately that made us even more dynamic. It’s working.”
Craig Smith pushed the lead to 3-0 at 12:31 on a one-timer of a pass by Steel, and Johnston made it 4-0 at 15:53 on a rebound in tight.
Dallas outshot Nashville 18-1 in the first period.
“It’s funny how it works, right?” Stars defenseman Ryan Suter said. “Some games, you dominate and you can’t buy a goal, and then some nights, it goes in. Tonight was one of those nights. The effort was there, so it starts with that, and then we were able to get some bounces.”
Miro Heiskanen made it 5-0 at 4:40 of the second off a wraparound ‘Michigan’ attempt by Johnston.
