The Penguins won 3-2, tying their Eastern Conference Final best-of-7 series 2-2, with Game 5 in Pittsburgh on Sunday (3 p.m. ET; NBC, CBC, TVA Sports).
"At the end of the day, I think they deserved to win more than we did," forward Clarke MacArthur said.
He wasn't alone in feeling that way.
"They were the better team tonight for two periods, and they deserved the game," Senators coach Guy Boucher said. "We deserved two games and we got two games. They deserved two games and it's 2-2. That's how it is."
The biggest problem, perhaps, was knowing that the Penguins were operating at less than 100 percent, a problem that magnified after Chad Ruhwedel sustained a concussion at 19:34 of the first period, leaving Pittsburgh with five defensemen. They already didn't have Justin Schultz (upper body) for the second straight, and have been missing Kris Letang (herniated disc in his neck) all postseason.
But the Senators didn't do enough, didn't make enough plays, didn't connect on passes, didn't play with urgency and didn't score on the power play (0-for-4). They got better as the game went on, and made their push, but it wasn't enough.
"We let them off the hook a little bit tonight with that," MacArthur said.
And when they fell behind, with the Penguins scoring at 19:14 of the first period (Olli Maatta), 7:41 of the second period (Sidney Crosby, power play) and 11:30 of the second (Brian Dumoulin, off the skate of Senators defenseman Dion Phaneuf), it was too much to overcome.
They fell behind even though they knew the Penguins would come out better and harder in Game 4.
"The game is about momentum and I feel like when the opposing team or we get momentum, one or the other, the team that seems to be on their heels is that, they're on their heels," goaltender Craig Anderson said. "It's almost like a panic mode, where you almost freeze because you're just caught off-guard.
"That was the way it kind of was the other night, when it looked like we were flying and they were flat-footed, and then tonight when we were flat-footed, they were going pretty good. It's almost like you just forget how to play briefly and that split-second hesitation makes you look really slow."
