Of late, the Kings have not found the right formula, and the lack of cohesion showed in Saturday's 4-1 loss to Chicago. They've won once in their last four games.
"We haven't lived up to that potential — hardly at all this season," Doughty said Monday. "We're not happy with the way we're playing. We know we need to turn it around immediately."
How often have they hit the optimum level?
"I don't really want to put a number on it — in case I'm wrong," Doughty said. "I would say about half of the games we've played well. I think we've gotten away with some games where we've won that we maybe shouldn't have won. There's a few games we've lost where we played well and didn't win.
"I'd say about half we've played well. That's the problem. We need to play well in 90 to 95% of the games. ... We need everyone to play well. It's not going to take just Kopi [Anze Kopitar] or Quickie [Jonathan Quick] or the back end to play well; it takes everyone."
Defenseman Alec Martinez, having sat out seven games because of an injured finger, continues to progress but could not offer a timeline. If he does not return against the Boston Bruins on Tuesday, the next possibility would be Thursday at Arizona.
"He's doing everything better, so meaning that he skated with the team and done all that stuff," Kings Coach Darryl Sutter said. "But everybody can skate with the team. It's being able to shoot and pass, and the next part of it will be the contact part of it."
Said Martinez: "I thought today was big in terms of the style of practice. We had battle drills and all that, to be able to test it that way and play more of a game-like situation in terms of getting my angles and my reads."
Kings right wing Marian Gaborik, who sat out Saturday's game because of an upper-body injury, did not practice. Kings Assistant General Manager Rob Blake said that Gaborik's injury was "similar" to an ailment he suffered earlier this season but not as serious. Gaborik's earlier injury kept him out of action for eight games.

Etc.: Kings forward Jordan Nolan's game misconduct was rescinded by the league Monday. Blake said it had been written up incorrectly and was merely a 10-minute misconduct. Nolan fought with Blackhawks forward Daniel Carcillo, a former King, with 1:25 remaining in Saturday's loss.
