"We got owned in our own zone," Oilers coach Ken Hitchcock said. "They are a [heck] of a hockey club and they've dialed it up through the last little bit, and they owned us in our own zone. They won the 1-on-1s, they knocked us out of the box, they won the net front. They owned us."
Melker Karlsson made it 5-1 at 2:41 of the third period, and Couture scored shorthanded at 8:25 off a pass from Evander Kane to make it 6-1.
"We came out [in the third] and we put them away," Kane said. "We gave up a couple late, but the game was over early in that third period. We came out hard and we kept our forecheck going and we spent a lot of time in their end. I thought we played a solid game."
Caleb Jones scored his first NHL goal at 10:40 to make it 6-2, but Melker Karlsson scored at 14:09 to push the lead to 7-2.
Draisaitl scored at 16:53 to make it 7-3, and McDavid batted the puck out of the air in front at 19:54 to cut it to 7-4.
"After you take a [butt] kicking like that, it should wake you up and realize you need to get things going in the right direction again," Oilers forward Milan Lucic said. "It's hard, but we had earned our way back into a playoff spot and it is on us that we are back on the outside looking in again. It's up to us to get ourselves back in it."
