Brett Kulak’s first goal since January will certainly be one to remember — for him, of course, and a building packed with fans who witnessed, in dramatic fashion, the Avalanche end a series at home for the first time in 18 years.

Kulak capped a wild comeback for the Avalanche, who trailed 3-0 midway through the second period. Colorado moves on to the conference final for an eighth time since relocating to Denver in 1995-96.

With Minnesota up 3-1, Jack Drury scored with 3:33 remaining to set the stage for MacKinnon’s goal with 1:23 left with the Colorado goal empty. The star forward sent a shot from the left side past Jesper Wallstedt and into a small space in the top left corner.

In overtime, Martin Necas took the puck, glided behind the net and back out front, where he found an open Kulak. Without missing a stride, Kulak lined it past Wallstedt.

Kulak was one of several late additions this season as he joined the Avalanche on Feb. 24 as part of a deal that sent Samuel Girard to Pittsburgh. Kulak became the 16th Avalanche player to score in the Minnesota series. 

He also was an unlikely OT hero. This was his first goal since Jan. 19 when he was with the Penguins, which also was his only goal of the regular season.

It was a rare series-ending win at home for Colorado, too. The last time the Avalanche won a series on home ice was 2008 against the Wild, when the team had Hall of Famers Joe Sakic and Peter Forsberg.

The Avalanche overcame a three-goal deficit to win a playoff game for just the third time in 53 tries since moving to Denver. The Wild had been 21-0 when leading a playoff game by at least three goals before the elimination loss.
