Max Pacioretty and the top line of Vegas are rolling right along.

Same with William Karlsson’s group on the second unit and right on down the lines.

Bottom line: The Golden Knights are operating four highly productive lines heading into their semifinal showdown with the Montreal Canadiens in a best-of-seven series that starts Monday in Vegas.

In all, the Golden Knights have seen 16 different players score so far in the postseason and 21 register at least a point.

“We’ve had so many contributions from so many guys,” said Vegas coach Pete DeBoer, whose team knocked off top-seeded Colorado in six games during the second round after holding off Minnesota in a seven-game series to open the playoffs. “We’re the sum of our parts.”

And those parts are firing on all cylinders, along with their blue-line pairings. The Golden Knights are far from top-line dependent.

Teams can strategize all they want to slow down Pacioretty, captain Mark Stone, Karlsson or Jonathan Marchessault. But that’s about the time a fourth-liner such as Keegan Kolesar or William Carrier will step up. Both had goals in Game 6 against Colorado.

Just doing their parts.

“Anyone that goes deep in the playoffs, they roll four lines and everyone can play and chip,” Carrier said.
