Defenseman Oscar Klefbom said there will be danger ahead if the Oilers repeat their Game 2 performance.
"The way we played wasn't the way we wanted," Klefbom said. "They outshot us a ton. If we play like this in Edmonton, it's going to be tough."
A 2-0 lead seems to create some nerves, and the Oilers are no exception.
"[2-0] seems to be a dangerous number for anybody that's competed in the playoffs this year, score-wise, series-wise," McLellan said. "We had an opportunity to get up mid-series against [the San Jose Sharks] and obviously didn't perform very well, but it wasn't 2-0. I thought there were a few details and characteristics that slipped into last night's effort that we saw in the 7-0 loss (to San Jose in Game 4 of the first round)."
Lucic and McLellan have been in similar spots in the past, when the left wing was playing for the Boston Bruins and the coach was with the Sharks.
"[In Boston], we were up 3-0 against the Flyers and we ended up losing in Game 7 (in the Eastern Conference Second Round in 2010)," he said. "And I know even Todd was up 3-0 against the [Los Angeles] Kings in 2014 and they ended up losing in Game 7 (of the first round) as well. No lead is comfortable, especially in a game against a team like this with some really high-end players, a team with a lot of pride and they have a coach that's really experienced and players that are really experienced. We can't take any situation lightly.
"Myself and the coaching staff, who have been a part of the losing end of historic comebacks, it's easy to pass those messages along."
