Hornqvist, who has missed four straight games with an upper-body injury, skated on his own without equipment before practice Monday. Ruhwedel, who missed Game 5 with a concussion, also skated on his own. Schultz, who has missed the past three games with an upper-body injury, had a scheduled day off the ice.
They're all day to day, coach Mike Sullivan said.
"Just going game by game helps you focus," Crosby said. "I think we evaluate our game pretty honestly regardless of a win or a loss. I think that can help with consistency in general."
What also helps is understanding what you're up against. The Penguins don't for a second think the Senators will still be reeling from the blowout in Game 5 when they take the ice Tuesday.
Momentum doesn't exist from game to game in the playoffs, especially when the opponent is facing elimination.
"It's about how you play the next game," Crosby said. "You don't get to the Eastern Conference Final without having the ability to bounce back. We know [Tuesday] night is going to be their best game and it has to be our best as well."
As in better than Game 5? A scary thought, indeed.
The Penguins think they can be better than they were Sunday, when they had a 4-0 lead after 20 minutes, 5-0 after 40 and 7-0 at the end. They were 3-for-3 on the power play and 4-for-4 on the penalty kill. They outshot the Senators 36-25.
"We might not win by 7-0 but there's always things we can do better," left wing Carl Hagelin said. "There were a few lapses in the second where we gave them entry to our zone a little bit too easy and gave up a few chances. Overall we played a good game. We have to focus on playing a better game."
