"We had a good shift," Eichel said. "I thought there were a lot of momentum swings in the game. It was just some little errors. We're giving too many pucks back to the other team when we have it. It's kind of just little simple stuff, but if we clean it up I think we'll be able to generate more offense and we'll spend a lot more time in their end."
The Sabres looked like a team with a purpose in the first 20 minutes, which saw them outshoot and outhit the Kings on their way to a 1-0 lead at the first intermission. Zemgus Girgensons opened the scoring for Buffalo, ending a scoring drought for the Sabres in LA that dated back to 2010.
The Kings took over in the second period and tied the game with a power-play goal from Brown, but the Sabres weathered the storm with some help from Lehner and came out strong again in the third.
"Everything we did well in the first period we got away from in the second," Sabres coach Phil Housley said. "We started to get our game back in the third. I thought we [controlled] the majority of the play in the third but again, it just comes down to special teams."
The Sabres had the top-ranked power play in the NHL to end last season, but it has been an area of concern through five games. They did nearly convert on once chance in the third period, but Jonathan Quick robbed Seth Griffith when he tried to one-time a feed from Eichel near the net.
The Sabres are now 2-for-19 on the power play this season.
"I think we've just got to mentally be a lot sharper," Kane said. "It's little things, breakout passes, not executing on our breakouts. When you don't do that, you're not going to have very good entries. I think that's where it starts and we need to find ways to gain possession in their zone."
Just like in their loss to San Jose on Thursday, the Sabres were left feeling like in spite of what they did well, small errors had cost them their first win of the season. Housley was generally happy with how they played in both games, and said if they continue to play that way then they'll turn a corner.
Their next chance is less than 24 hours away, against the Anaheim Ducks on Sunday.
"It's frustrating," Kane said. "We're trying to get our first win of the season. We.ve got a game tomorrow and we've got to try to cut the cord here and focus on that and not have this linger over to tomorrow night."
