Guentzel has seven points (one goal, six assists), building on his impressive run last postseason, when as a rookie he had 21 points (13 goals, eight assists) in 25 games.
Malkin is up to five points (three goals, two assists), including four in the past two games. Letang has four points (one goal, three assists), including three in the past two games. Kessel has three (one goal, two assists), all in the past two games.
"Usually if we need a momentum change or something of that nature, it's usually our leadership group that goes out there with a second-effort shift or a really good shift … or a big goal for example," Sullivan said. "That's what these guys have shown an ability to do."
In fairness to the Flyers, they played without arguably their most irreplaceable player, center Sean Couturier, who missed Game 4 because of a lower-body injury sustained in practice Tuesday.
But Couturier didn't make up for seven goals in Game 1 or five goals in Game 3. His presence might have helped the Flyers come out with a better start Wednesday, but the way the Penguins are going, the blowout likely would have happened anyway.
"I can't say any bad words tonight," Malkin said.
They haven't dispatched the Flyers yet, though. Game 5 is back in Pittsburgh on Friday (7 p.m. ET; NBCSN, CBC, TVAS, ATTSN-PT, NBCSP).
"You always look to match that urgency, that desperation to get that fourth one," Crosby said. "We understand that. We expect a tough game at home, so we have to be ready for that."
The Flyers likely will make it tougher than it's been on the Penguins in Game 5.
It might not matter.
