Nathan MacKinnon extended his point streak to 18 games with an assist, Alexandar Georgiev stopped 24 shots and the Colorado Avalanche cruised to a 4-1 victory over the Arizona Coyotes on Saturday night. Bowen Byram opened the scoring in the first period before Colorado pulled away in the second behind goals from Valeri Nichushkin, Josh Manson and Fredrik Olofsson. “The second period is a template of how we should and want to play,” said Avalanche coach Jared Bednar, whose team has won three of four heading into the NHL’s holiday break.
