The Detroit Red Wings look robotic, players are squeezing their sticks too tightly and not enjoying themselves.

Those were captain Henrik Zetterberg’s observations after yet another loss, 2-0 Tuesday to the Nashville Predators at Joe Louis Arena.

The Red Wings are winless in seven (0-2-5), their longest slide since their final seven games of 2001-02 (0-3-2-2, W-L-T-OTL). They are winless in their past eight home games (0-2-6).

Zetterberg believes a lot of their problems are mental.

“When you’re in a slide like this you shouldn’t think as much, you should just go out and play,’’ Zetterberg said. “Right now it’s like we’re squeezing our sticks too much. We’re not really playing the way we should.

“I think we’re more like robots out there now. We’re not being creative when we get our chances. We have to get back to playing the way we should. Go out and relax a bit and enjoy the moment. I think we’re not enjoying playing out there.”

Marek Mazanec had fun. Making just his fifth NHL appearance, he stopped 27 shots for his first shutout. The offensively challenged Red Wings (9-6-7) made his job easy by generating few quality scoring chances.

“I thought it was too easy for him,’’ Niklas Kronwall said. “We had a couple of chances, but we have to find a way to generate a lot more than that.’’

Red Wings coach Mike Babcock likened this game to playing on a muddy track.

“I didn't think either team generated much offense,’’ Babcock said. “I think from a fan's point of view, it was probably an ugly game, just grinding out there. We got to find a way besides the one group to generate.’’

To make matters worse, the Red Wings lost defenseman Danny DeKeyser to a separated left shoulder less than four minutes into the game. He is out at least 1-2 weeks, perhaps longer.

Shea Webber’s power-play goal with 4.8 seconds remaining in the first period opened the scoring. Gabriel Bourque added what amounted to an insurance goal at 7:13 of the third.

The undisciplined Red Wings were shorthanded six times.

"We can't take the penalties. It kills you,’’ Babcock said. “We can't take slashes and hooks and stuff like that, especially if they’re not in your zone. If it prevents a goal, it’s one thing, but we got to be more disciplined.’’
