Henrik Zetterberg was at a loss to explain why the Red Wings continue to be outworked in the first period of games.

The latest example was Wednesday night, when the Predators scored 3 minutes into the game and led, 2-0, after 20 minutes. The Predators extended their lead to 4-0 in the second period and beat the Wings, 4-1, at Joe Louis Arena.

"We've gotta find a way to find that excitement," Zetterberg said. "Usually, we get started in the second and third. We just gotta go out and play from the start. It will help us and make it a lot easier if we're not playing catch-up hockey all the time."

The Wings are 6-13-3 when they trail after the first period. They have been outscored, 57-48, in the first period this season. They've outscored opponents, 63-54, in the second, 56-43, in the third.

"We're not doing the little things right," Zetterberg said. "Instead of making the easy pass ... maybe we're trying to do something too difficult and not winning hockey games."

Zetterberg said it was embarrassing the way they've played lately, and said they needed to "trust each other" and stop trying to do another teammate's job.

What, specifically, was Zetterberg embarrassed about?
