McDavid was already seeing the long-term picture after the defeat.
"You look at any team that's won and been good for all the years, and it starts with a disappointment," he said. "We took a huge step forward.
"If we'd have told you we'd have taken the Ducks seven in the second series back in September, I don't think anyone would have believed us for a second. We managed to do that. We can hold our heads high about that. Obviously it's not the outcome we wanted. I believed in this group. We'll be back."
Edmonton hadn't qualified for the Stanley Cup Playoffs since 2006 and had 70 points last season (31-43-8), second-fewest in the League. It had 103 points (47-26-9) and finished second in the Pacific Division this season.
"I don't think anyone thought we'd be here, one period away from the conference finals," said goalie Cam Talbot, who made 28 saves in Game 7 and had a 2.48 goals-against average and a .924 save percentage in the playoffs. "I'm proud as [heck] to be a part of this group right now and I'm looking forward to the future with this team.
"From last year, finishing near the bottom of the League, then this year, we came out strong and we grew as a group. You could see we took that next step this year. I don't think anyone thought we'd be here, one period away from the conference final, so I'm proud to be a part of this group and looking forward to a future with this team."
Oilers forward Leon Draisaitl, who had a major impact in the second round with 13 points (five goals, eight assists) in seven games, said the education of this year's playoffs will be invaluable.
"We had a lot of guys who never went through something like this, and now we have guys who know how to deal with it next year if we make the playoffs," Draisaitl said. "I think that will help us a little bit. They had the experience factor on us again and we took them to seven games. One goal was the difference."
