Avalanche center Nathan MacKinnon gets into heated exchange with coach Jared Bednar

There is a lot of frustration building up in Colorado.

Nathan MacKinnon — the Avalanche’s alternate captain and second-leading scorer — got into a heated exchange with head coach Jared Bednar in Colorado’s 5-3 loss to the Flames on Wednesday.

Gabriel Landeskog was visibly trying to calm MacKinnon down as he was getting animated on the bench. He was so heated he actually fell off the pine and had to be helped back up.

MacKinnon then appeared to mouth “do your f—ing job” at Bednar.

The Avalanche started the year on fire opening the season with a 6-1-2 record through their first nine games and a 16-6-5 mark through 27. But, since then, Colorado has gone 4-10-3 over its last 17 games and now sits in a wild-card spot after leading the division early in the year.

MacKinnon, Landeskog and Mikko Rantanen have combined to lead the NHL in points on a line this season (185). All three players have at least 20 goals and 20 assists, but not a single other player has more than 12 goals on the team and only two have put more than 10 into the net.

Colorado has been rumored to be on the lookout for help in the trade market, and with the lack of scoring from the team’s second, third and fourth lines, it might need to make a move soon.
