Defenseman Oscar Klefbom pointed to another disappointing start against the Red Wings, who scored on two of their first four shots to take a 2-0 lead at 9:10 of the first period Sunday.
"Even if we get a couple of goals-against we feel pretty good from the start, but have to find a way to stay in the game," he said. "Right now we're just folding our cards too quickly."
Another issue that has given the Oilers trouble this season is cohesion, which has made their game look hesitant. It's surprising because team play and quickness was among their best qualities last season.
"We're not playing fast enough," McLellan said. "When you describe fast you think about Connor [McDavid] flying down the wing and beating somebody 1-on-1. That's fast. But the group has to play fast as a whole. We're not quick enough to loose pucks. We don't keep a lot of plays alive in the offensive zone.
"Some of that is actual skating pace. A lot of that is just reading and reacting. I don't think we defend quick enough. Our penalty kill is not reacting fast enough, our power play is not reacting quick enough. There are some plays there, a lot of these open nets are laying there, we're just a fraction slow on firing the pucks."
McLellan normally turns to McDavid and linemates Leon Draisaitl and Pat Maroon when the Oilers need a spark. But against the Red Wings, McDavid played a season-low 15:55, including 4:25 in the third period.
"I didn't think they were having a real good night," McLellan said. "We've played 13 games and they've probably been our best line in 11 of those games and they carried the team and some nights they're going to have an off-night."
McDavid, who leads the Oilers with 16 points (five goals, 11 assists), is averaging 21:55 of ice time in 13 games this season.
"I really don't know what to say," McDavid said. "The game was kind of out of reach. Obviously you don't like [not playing much in the third period]. It is not very fun to sit on the bench. But that's what it is.
