The best-of-7 series is tied 2-2 with Game 5 at Pittsburgh on Thursday (8 p.m. ET; NBC, CBC, SN, TVA Sports).
"I think we're just focused on tomorrow," Penguins captain Sidney Crosby said after practice at UPMC Lemieux Sports Complex on Wednesday. "That's how we're looking at it. We did some good things last game, so if we can build off of that, we'll put ourselves in a good spot. But we've got to be a little more consistent and make sure tomorrow's our best game.
"I think at this point of the series, both teams are pretty desperate, and they understand where we're at and the situation. I would expect both teams to be desperate."

Penguins coach Mike Sullivan balked at the idea they are desperate heading into Game 5.
"I don't know that we feel we're against the ropes," he said. "I think we have to win a game. And that hasn't changed.
"Desperate is a funny word for me because it gets thrown around our game a lot and it always has a connotation of hopelessness. And I don't believe that's the word we want to use to describe our team.
"I think we've got to play with urgency. I think we've got to play determined. I think we have to play with conviction. And I think when our team plays that way, we're at our very best. Our focus is really, quite honestly, on one game, and that's the approach that we have to take.
"And we've got to keep our mindset just focused on that short-term approach, just that on-task mindset of just controlling what we can and staying in the moment. That's where we're at, and that's all we've talked about with our team over the last couple of days."
