Zach Hyman made it 2-0 at 1:13 of the second period, stuffing in a rebound with a backhand at the top of the crease after a shot by Nugent-Hopkins.
Brown pushed it to 3-0 at 6:53, finishing a rebound below the left circle after Hill kicked away Draisaitl’s shot on a 2-on-1 rush.
Draisaitl made it 4-0 at 10:46, tapping in a backhanded cross-crease pass from Darnell Nurse at the left post.
Corey Perry pushed the lead to 5-0 at 12:53 with a snap shot from the high slot past Hill’s glove through traffic.
Victor Olofsson cut it to 5-1 at 15:35 with a one-timer in the slot off a pass from Tomas Hertl below the goal line, and Ivan Barbashev redirected a shot in front to make it 5-2 at 16:01.
“We started turning the puck over between the blue lines and they all end up in our net,” Barbashev said. “There were a lot of details in our D-zone, we’d been on a really good stretch defensively in the past five or six games and have done a really good job. Today, it just wasn’t there, those little details that got away and that’s how they scored all five goals, basically.
“It’s like a little wake-up call, we’ve got to just get back to our normal game and regroup. We’ve just got to turn the page and be better.”
Brett Howden scored short-handed to make it 5-3 at 1:00 of the third, stealing the puck from Skinner behind the net and putting it into an open goal.
Jeff Skinner responded 38 seconds later to make it 6-3 when he found a rebound in the slot and beat Hill with a snap shot.
“You can’t give up the next goal, obviously. And obviously they’re a good hockey team, they’re probably going to be on alert after that,” Cassidy said. “They’re going to be back on their toes, it’s human nature to let the foot off the gas a little bit when you get ahead, we’ve been there and done it.
“But we gave up the next one, unfortunately, and that probably took the wind out of our sails.”
NOTES: It is Draisaitl’s sixth multipoint streak of at least five games in his career, passing Sidney Crosby of the Pittsburgh Penguins, Nikita Kucherov of the Tampa Bay Lightning and Nathan MacKinnon of the Colorado Avalanche for second-most among active players. McDavid has the most with 12 multipoint streaks of at least five games. … Jack Eichel (nine goals, 31 assists) set the Golden Knights mark for fewest games to 40 points in a season, previously held by Mark Stone in 2020-21 (32 games).
