Vegas misses Stephenson's speed, and his absence has forced DeBoer to tinker with the lineup, trying Roy, Tuch, Keegan Kolesar and Tomas Nosek at times on the top line between Pacioretty and Stone.
"We've played basically this series without our No. 1 centerman so far," DeBoer said. "Obviously want to get him back in the lineup, and I think that's on the horizon. But I give credit to the guys who've stepped in there and done the job.
"You take somebody like that out of anybody's lineup, and it affects your team. I look at [the Canadiens] in Game 1 without [defenseman Jeff Petry] in their lineup. That changes how your team plays. It changes the structure of your team, your depth, and to our guys' credit, we've found a way. It hasn't maybe looked as pretty as everyone would like it to look, but we've found a way."
Some scoring droughts go back further than this series. Stone has one goal in his past 12 games, Tuch one in his past 13, Smith in his past 14. Stephenson has no goals in 14 games in the playoffs.
The power play is 0-for-11 against Montreal and 4-for-39 in the playoffs (10.3 percent, worst among the 16 playoff teams).
The top forwards have contributed in other ways. Karlsson set up McNabb's tying goal at 10:37 of the third period in Game 4 and he leads the Golden Knights with three assists in the series. Pacioretty and Tuch set up Roy's winning goal at 1:18 of overtime. Each has two assists in the four games.
"I think the way we activate (on defense) is important," Pietrangelo said. "I think some games, some series, you're going to score more than others. I think we're getting those opportunities. We did all season long. It's just right now the group collectively, we're finding the back of the net, which is important.
"I mean, obviously, there's a lot of talk about the forwards not scoring, but they're creating opportunities. They're creating those plays allowing us to score those goals. Obviously, we've got to continue to find a way to create some more. They're playing tight defensively. The goalie's playing well."
