"You've got to base it on the whole camp, not one period, not one shift or one game," Kings coach Darryl Sutter told the Los Angeles Times.
Anaheim's Viktor Fasth stopped 23 of 26 shots – including a penalty shot against Kyle Clifford in the second period -- before being replaced by rookie John Gibson, who allowed three goals on eight shots.
Dustin Penner, who spent the past two seasons in Los Angeles, was reunited with Corey Perry and Anaheim captain Ryan Getzlaf for the first time since the Ducks won the Stanley Cup in 2007.
"They played fairly well, and we played fairly poor," Penner said. "It's preseason, and it's a lot of guys' first game. But with that being said, it's not an excuse. It's a matter of fact. There were a lot of things we could've done more efficiently. Number one is compete. They had too many easy shots, and made it too hard on our goalies to make saves."
