"It hasn't gone our way throughout the season at certain points but we always responded," McLellan said. "And that's what the regular season is for, to build a base, not only a systematic and conditioning base, but a mental base, too, for these types of situations. We've been good in the playoffs responding, but not great. Great would mean we're up by one, not down by one."
The adversity Edmonton is facing has not clouded general manager Peter Chiarelli's view that the Oilers have progressed and grown.
"That was our objective this year," Chiarelli said. "I've seen a lot of it. It doesn't really feel great right now. I've seen resilience. These are trying times when you get games like [Friday] and Game 4 (also a 4-3 loss in overtime). A lot of growth.
"You see the younger guys playing under duress. You see them making a lot of plays and mistakes. And I know in two, three years I'm going to look back on this and say, 'That was great for us.' I know that. One hundred percent certain. It's just hard to make that determination now."
Among the reasons for that are two video reviews for goalie interference that have not gone Edmonton's way.
A goal by Ducks center Ryan Getzlaf 1:37 into the second period of Game 4 was upheld after a coach's challenge. Anaheim forward Rickard Rakell's goal that tied it 3-3 with 15 seconds left in the third period of Game 5 stood after a situation room review for goalie interference.
