The Canadiens then trounced Los Angeles 7-3 behind Pat Hughes' hat trick and skated to a 5-5 deadlock with Philadelphia, which was 0-1-3 for the week. Chicago maintained a two-point lead over the Canucks in the Smythe Division despite losing two of three, including a 4-2 decision in New York to the Islanders, who remain unbeaten after 23 games this season on home ice and lead the NHL in points and goals.
