"Obviously, a healthy Kevin is different than somebody hurt," Danault said. "But, yeah, we were missing him at the beginning of the series for sure. But he came out pretty strong for us and he played well."
Kostin put Edmonton ahead 4-3 at 10:54 of the second, scoring from the slot after Kings defenseman Drew Doughty's pass to Mikey Anderson along the boards behind the net skipped over his stick.
"They find a way to score some big goals, and their bottom six guys were huge for them. I think that was the turning point there," Danault said. "We played a solid game, but they played the whole game and got rewarded."
