New York failed to capitalize on several scoring chances during the first period of its 3-0 loss Sunday at Consol Energy Center, allowing the Penguins to escape to a scoreless intermission.
The impact wasn't noticeable.
"The power play had some looks. It could've given us momentum," Vigneault said. "We didn't finish, and the power play ultimately is my responsibility. I have to find the right trigger points here to make it work, and I'll spend the night trying to figure it out.
"I felt that they're a team that plays a real tight gap, and managing the puck through the neutral zone is one area that we need to be better."
