DETROIT - Rolling, not rusty.

The Detroit Red Wings looked as sharp as they have throughout the playoffs — and perhaps in any postseason — jumping out to a big lead and beating the Dallas Stars 4-1 Thursday night in Game 1 of the Western Conference finals.

Detroit played for the first time since sweeping the Colorado Avalanche a week earlier.

“They were scared, just like the coaches, that they wouldn’t be ready,” Red Wings coach Mike Babcock said. “A little fear never hurt anybody.”

Dallas, meanwhile, looked tired.

The Stars advanced past the San Jose Sharks in one of the longest games in NHL history — ending Monday morning in a fourth overtime — after playing three other OT games in the series.

“Whether it’s fatigue or whatever, we just weren’t at the level we needed to be,” coach Dave Tippett said.

Johan Franzen, Brian Rafalski and Tomas Holmstrom scored power-play goals for Detroit, which led by four in the second period before coasting to its seventh win in a row.

Nicklas Lidstrom helped Detroit win three Stanley Cup titles between 1997-2002 and said these Red Wings are as dominant as ever.

“It’s been a balanced scoring and strong team defense,” Lidstrom said. “I think it’s very comparable to some of the teams we had back in the ’90s.”

After Valtteri Filppula put the top-seeded Red Wings ahead 4-0, Brenden Morrow scored with a minute left in the second period to prevent the fifth-seeded Stars from getting shut out.

“We had a good two or three shifts to start the game,” Morrow said. “But then the ice got tilted the other way.”

Game 2 is Saturday night at Joe Louis Arena, where Stars goalie Marty Turco is 0-8-2 in his NHL career.

Turco, who made 27 saves, was serenaded with jeers of “Turrr-co! Turrr-co!” by fans early and often.

But Tippett tried to deflect blame for the blowout.

“A lot had to do with the team in front of him,” he said.

Detroit’s Chris Osgood turned away 20 shots, improving to 7-0 as a starter since replacing Dominik Hasek in Game 4 against Nashville.

Dallas upset the defending Stanley Cup champion Anaheim Ducks in the first round and then topped the second-seeded Sharks after starting both series with two road wins.

The way the Franzen-led Red Wings are playing, they’re going to be tough to beat in any rink.
