"I think road hockey was getting the best of us a bit," Hellebuyck said. "I thought we prepared the right way. So we have to take a good look, take a step back and continue to build."
Maatta gave Pittsburgh a 1-0 lead on the power play with a slap shot that deflected off Winnipeg forward Blake Wheeler's stick at 14:19 of the first period. It was Maatta's first goal this season and his first in 57 games since he scored twice against the Boston Bruins on March 1.
"They got a couple good bounces," Wheeler said. "They were just a little step quicker, kind of, in everything they did. In the offensive zone, we had a ton of time there. They blocked a ton of our shots. ... Obviously, they did a good job of getting in those lanes and doing the things they needed to do. We were just a half step off."
Cullen scored 33 seconds later, making it 2-0 at 14:52. After Zach Aston-Reese shot off Jets forward Patrik Laine, the puck hit Cullen's head before going in.
