VOORHEES, N.J. - The Penguins have the Flyers on the canvas in a headlock.
The faces of the guys who wear orange and black are turning purple, and unless they put up a courageous fight as they did in Game 2, they will tap out of this best-of-seven series after just five games (see story).
General manager Ron Hextall spoke to the media for the first time since the series started and believes the Flyers have displayed a lack of mental fortitude through the first four games.

"A lot of it is mentality," Hextall said. "We need to be stronger if a bump goes the other way. We need to be stronger and bounce back and create energy going back our way. The playoffs are a series of momentum [swings] - within a period and within a game. We need to do a better job of bringing the momentum back our way."
So where exactly does that start? The return of Sean Couturier would help considerably.
After sitting out Game 4's 5-0 loss, the Selke Trophy finalist hasn't ruled out playing in Game 5 after skating Wednesday and Thursday on his own. Hextall said Couturier would travel to Pittsburgh and nothing more than that.
"I'm feeling better every day, and we'll see how I feel tomorrow," Couturier said. "It's really on me to see how I feel every day and hopefully, it keeps getting better. It's really up to my body to see how it keeps progressing."
Dave Hakstol switched up his lines once again Thursday, most notably installing Valtteri Filppula onto the top line with Claude Giroux and Jakub Voracek and breaking up the top defense pairing of Ivan Provorov and Shayne Gostisbehere.
Robert Hagg is also expected to make his series debut, playing alongside Andrew MacDonald as fellow rookie Travis Sanheim will serve as the healthy scratch.
"About time," Hagg said. "I'm looking forward to it tomorrow. Hopefully, I can bring something to the team, some energy. I think it's perfect and I can't wait to go in and show what I can bring to the team."
"He brings a different element than a couple of guys in the lineup if we're so inclined to make that change," Hakstol said. "We haven't generated very much over the last five periods, but at the same time, we've given up quite a bit in some of the harder areas."
Toward the end of Thursday's 45-minute practice, Giroux gathered his teammates around and delivered a speech he hopes can galvanize the Flyers for Game 5 and bring the series back to Philadelphia for Game 6.
"I think it's believing in ourselves," Giroux said. "All year we've done that, and we've talked about it before. You lose 10 in a row and find a way to make the playoffs. Tomorrow's a big game for us, and if we're going to go down, we're going to go down swinging."
• Speaking on the collision with Radko Gudas, Couturier said, "We've done this drill all year. It was bad timing and a fluke accident. There's no one to really blame, and I should have maybe had my head up there."
• Hextall believes Couturier should be the Selke Trophy front-runner based on his outstanding 2017-18 season.
"I think he should win it," Hextall said. "I know those other players fairly well, and yes, I watch Coots on a daily basis, but the two-way game that he brings to our team is in my mind, the best in the league this year."
• Penguins forward Patric Hornqvist will miss his second straight game.
