Patrice Bergeron left the puck at the top of the right circle for Marchand, who skated into the slot and fired it past goalie Semyon Varlamov to extend his franchise record with 14 career overtime goals.
Nathan MacKinnon scored his 29th goal for Colorado, tying Gabriel Landeskog for the team lead. Varlamov had 33 saves as the Avs lost their seventh in a row (0-3-3) but earned a point with a third straight overtime loss.
MacKinnon gained control of the puck in the corner before charing the net and beating Halak high on the glove side with 32.1 seconds left in the first.
Boston tied it on Moore’s goal nearly four minutes into the second. The veteran defenseman’s wrist shot from atop the left circle found its way past a screened Varlamov for his third goal of the season.
MacKinnon’s perfectly-timed exit from the penalty box during a Bruins power play midway through the period resulted in a breakaway, but he hesitated and jammed the puck against Halak’s blocker.
Moore nearly scored another when he dumped the puck into the Avs’ zone, only to have it take a wild bounce off the glass and zip past an unsuspecting Varlamov with 24.1 seconds left in the second. Moore stared in disbelief as the referees waved it off, saying the puck went out of play after hitting the curved glass next to Boston’s bench.
