"I thought we were okay in the first, I thought we were the better team, but we just can't seem to find a way to play that over 60 minutes," Leon Draisaitl, who tallied an assist, said post-game. "You have to play your game for 60 minutes, and we didn't do that tonight."
The Oilers impact on the power play was limited to one goal on seven opportunities, including a trio of advantages in the final five minutes.
Despite Ottawa's less-than-favourable spot in the standings and the Oilers own position atop the Pacific Division, there wouldn't be any guarantees.
"At this point, we're on a winning record," defenceman Adam Larsson said. "I think we need to find a way to not get too high and too low. You can't win them all, but a game like this we should recognize when things aren't going our way. I think we can play a lot smarter."
