The Los Angeles Kings’ sputtering offense needed a quick fix. Dustin Brown, Anze Kopitar and defenseman Tom Preissing helped provide it, making goalie Jonathan Quick’s NHL debut an absolute breeze. Brown had two goals and an assist, Preissing scored twice during power plays and Michal Handzus had a short-handed tally in the Kings’ 8-2 victory over the Buffalo Sabres on Thursday night.
