"We weren't disappointed with the way the power play has been playing," Doughty said. "It sounds stupid, we had zero goals up until now, but we were getting good chances, hitting posts. Just not getting it done, but we knew it was going to come if we stick to the basics."
Zemgus Girgensons and Jack Eichel scored for the Sabres (0-4-1), who lost their fourth straight game in regulation. Lehner made 26 saves.
Defenseman Oscar Fantenberg got his first NHL point with an assist on Toffoli's goal for a 2-1 lead at 7:09 of the third period. But Eichel followed up on his initial shot for his fifth goal to make it 2-2 at 9:06.
The Sabres had the better of the play to start the third period, but Quick robbed Seth Griffith at 3:59 as the Kings killed a tripping penalty against Andy Andreoff. Instead of Buffalo retaking the lead, Los Angeles held and set the stage for Toffoli's second goal.
"Quickie made an absolutely stupid save there," Toffoli said. "I think that kind of changed the momentum and made us realize that it's time and Quickie's battling. After that, we kind of stuck together and score just big goals at the right time."
