There wasn't going to be a concession speech Thursday night, but the Kings know through four games they clearly are submitting to the Blackhawks' talent advantage.

"We're not a speed team, we have to be more physical," Kings defenseman Drew Doughty said after the 3-2 loss in Game 4 of the Western Conference finals put them at a 3-1 series deficit. "We could've been more physical."

He was particularly unhappy the Kings let Patrick Kane and Marian Hossa get goals.

"(Their) big guys got goals and we have to take those guys out of the game," Doughty said. "We need to do more."

The Kings' fall from two leads Thursday was worsened by their 14-minute stretch without a shot on goal in the third, which ended with less than 90 seconds remaining.

The Blackhawks blocked 11 Kings' shots.

"We have to find a way to get more pucks to the net," Kings captain and center Dustin Brown said. "You have to get it by at least the first guy because they have layers."

Kings defenseman Rob Scuderi indicated the Blackhawks' knack for forcing turnovers has occupied thoughts. The Kings had eight giveaways in Game 4.
