DETROIT -- The Detroit Red Wings throughout the season showed the ability to roll four lines, mix and match parts with instant success and get scoring from many sources.

That potent offense -- only the Vancouver Canucks scored more goals during the regular season -- was missing in the first two games of the Western Conference semifinals against the San Jose Sharks.

The Red Wings have scored two goals, only one by a forward. That is why they are down 0-2 heading into Wednesday’s Game 3 at Joe Louis Arena.

Coach Mike Babcock shuffled his lines Tuesday in practice and appeared ready to make at least one lineup change. And he issued a challenge to his forwards.

"I want more out of our forwards," Babcock said. "I want us to spend more time in the offensive zone and sustain pressure. I think we can back-check harder and I think we can be harder on 50-50 pucks just all over.

"That’s a challenge to all our forwards, and it doesn’t matter who’s playing with who."

Detroit’s forwards must exert their will on the Sharks, be harder to play against, wear on the defense and apply more pressure on goaltender Antti Niemi. That is what San Jose’s forwards, with their ability to hang onto the puck and cycle, have done to the Red Wings and goalie Jimmy Howard, whose strong play has given his team a chance to win both games.

"We need more than one goal," Detroit forward Pavel Datsyuk said. "We need to make more traffic on (Niemi). They so far have had it easy playing against us. We need to shoot the puck more and make more traffic.

"We’re pushing, but we’re not finishing. We’re too casual. We need more shots going to the net."

Datsyuk has been terrific, controlling the puck like he usually does and setting up both goals. Every other forward can step up. With Johan Franzen, Danny Cleary, Todd Bertuzzi and Tomas Holmstrom, the Red Wings have enough bulky forwards with scoring ability who can make it harder on the Sharks.

"We’ve got to get some consistent pressure in the offensive zone, be good defensively," Cleary said. "Our focus is to get back to the way we’re capable of playing.

"You got to at least generate more offensive opportunities, which can lead to them taking a penalty or a momentum swing."

Babcock on Tuesday split up Datsyuk and Henrik Zetterberg, who looked better in Game 2, his second game back after suffering a sprained knee on April 6. Zetterberg was practicing with Cleary and Bertuzzi. Datsyuk was flanked by Franzen and Holmstrom.

The Red Wings also need more physical play and energy from their third and fourth lines. Kris Draper, a healthy scratch the first two games, will make his series debut in Game 3.

"We’re not playing how we have to play," center Darren Helm said. "From top to bottom, we’re not doing a good enough job getting the puck deep, getting shots at net and being hard at the net. It’s hard scoring goals when you’re playing in you’re own zone the whole game.

"We’re just not playing as physical as we should be."

The Sharks, who went 3-0 on the road in the first round against the Los Angeles Kings, expect a huge push from the Red Wings.

"They’re going to try to play more in our end, get on our D quicker," forward Logan Couture said. "We’ve been able to break out pretty quickly on them."

The Sharks have won 10 of their past 12 games against the Red Wings, including six of seven in the playoffs.

"They seem to get up for us," Red Wings defenseman Brad Stuart said. "We need to use that as a bit of a wake-up call. Enough’s enough. The time is now."

Couture said his team isn’t in Detroit’s head.

"They’re a veteran team, they know how to win championships," Couture said. "It’s just the way it goes sometimes, where you kind of have a team’s number. But things can change so quickly in this game."
