POST-GAME UPDATES
Inside The Oilers Blog
Cody Eakin equalized the score shorthanded before Max Pacioretty and Jonathan Marchessault put the Golden Knights ahead by a pair within the first five minutes of the middle frame.
"We just have to be mentally stronger," McDavid said post-game. "If something goes wrong, we have to be able to brush it off and move on. We give up a bad shorthanded goal and it kind of deflated us. They were able to capitalize on two more and then we're behind the eight-ball.
"We have to find a way to limit those lows."
Goaltender Cam Talbot would allow six goals on 30 shots, falling to 0-5-0 in his last five games as he still waits for his 100th win as an Oiler.
"Any time a goaltender gives up six, the group is looking for another save," Oilers Head Coach Todd McLellan said. "But we were porous around him. There were a number of pucks where we were standing around and watching, and they just chopped at it and the puck found a way into our net."
The defeat condemns the Blue and Orange to six losses in their past seven games and a record of 9-10-1.
"We have to realize by playing the right way and paying attention to details, our offence is going to come," Oilers forward Alex Chiasson said. "I think right now we might be on the other side of the puck trying to wait for a mistake or a bounce to come our way, but right now they aren't coming.
"We've got to come back to the foundation of our game and make sure we play the right way for 60 minutes. We haven't been able to do that for the last little bit, and every time we go to sleep for a couple minutes the puck ends up in the back of our net."
Chiasson's power-play goal in the second period made it seven goals on the season for the Montreal, Quebec product. Leon Draisaitl had a goal and assist, and Drake Caggiula recorded two assists.
Just 52 seconds into the game, it would be that man McDavid providing the early spark for the Oilers once again. Gliding away from goal with a Vegas player on his hip, the Oilers captain still found a way to get a stick on Matt Benning's tip and deceive Marc-Andre Fleury, who was caught sliding the wrong direction. Caggiula would record the secondary helper on McDavid's 12th goal of the season.
