O'Reilly scored a rebound to tie it 2-2 at 5:07 of the second.
"I thought we did a really good job coming back when they tied it and the game could’ve gone either way at that point, but we responded well," Cronin said. "That, to me, is the reflection of a team that kind of believes in themselves."
Harkins sent a rebound past Saros to put the Ducks back in front 3-2 at 10:46, and Zegras scored off another rebound to extend the lead to 4-2 at 11:48.
"We gave up two goals in a minute," Brunette said. "All of those things that really equate to losing hockey, we kind of did tonight."
McTavish capped the scoring in the second period with a one-timer from the right circle while on a power play to make it 5-2 at 14:20.
"We got away from our identity," O'Reilly said. "We talk about being harder to play against and we didn’t manage the puck very well. We were trying to find the east-west plays. When we did put it behind them and take care of the puck, that’s where we generated our offense from. It’s tough. We've got to reset and get back to us. For myself, too, more leaders on the team got to lead the way. Especially grab a hold of when it’s a game like that and simplify and get back to what we do. We’ll fix it and get back to it."
