In the Cup Final, the top line has eight points. Smith has four points (two goals, two assists), and Karlsson has two (goal, assist). Marchessault has two assists and hasn't scored a goal since May 16, when he scored two in Game 3 of the Western Conference Final against the Winnipeg Jets.
However, Golden Knights coach Gerard Gallant said he liked how the first line played Monday for the most part.
"They came out and started the game the way we wanted to start the game," Gallant said Tuesday. "A couple of unfortunate bounces, and we're down 3-0. Our guys are playing hard, they're playing well, and they'll be ready to go.
"Like I said, Washington is a good hockey team. Their top line is a pretty tough line that's playing against them every night, too. So, it's a battle for ice out there, and we're trying to do the best we can. Hopefully a couple of breaks and the goal by Reilly Smith last night will get us going."
The top line isn't the only one struggling. Gallant adjusted the lineup entering Game 4, playing forward Tomas Tatar on the third line with Cody Eakin and Ryan Carpenter and moving Alex Tuch to the second line with James Neal and Erik Haula. Vegas also had some bad breaks, the biggest when Neal hit the far post on its first power play in the first period.
"Just maybe some puck luck or just not bearing down," Tuch said. "It happens. It's hockey. It's a game of inches and sometimes it doesn't go your way and it hasn't so far. But hopefully we're able to turn that around for Game 5."
Despite the result, the Golden Knights said they played the right way in Game 4. But moral victories only go so far. Vegas needs goals and a Game 5 victory, and needs its top line to produce.
As Marchessault said, it starts with them.
