"It was just overall doing the right things, starting the game as a team, moving our feet and keeping it simple," Byfuglien said. "I just got across the (blue) line and (you want to) get shots to the net early and one happened to go in."
Byfuglien also made a key play to help the Jets go ahead 2-0 when Patrik Laine scored a power-play goal at 6:49 of the first.
He stretched out with one hand on his stick and kept Brayden McNabb's attempted clear inside the Golden Knights zone, stopping the puck right on the blue line. The Jets then worked the puck to Laine at the left face-off circle for a one-timer.
At 9:54 of the second period, it was Byfuglien's power-play wrist shot from the point that Scheifele deflected for a 4-1 lead.
Byfuglien played a game-high 24:44 with three shots on goal and two blocked shots. The Golden Knights took a few runs at the big defenseman but often bounced off him, including forward Alex Tuch in the third period.
"That game that you saw and he's certainly played others, you saw the Dustin Byfuglien spectrum," Jets coach Paul Maurice said. "He can shoot the puck a ton, he can make soft-hand plays and he can be as big and strong as you want out there. And he's been very consistent with his game."
Coming off a 5-1 victory in Game 7 of the second round against the Nashville Predators on Thursday, Byfuglien said Winnipeg's start in Game 1 against Vegas was a product of remaining in the form necessary to eliminate the Presidents' Trophy winners.
