Nathan MacKinnon was not a happy camper after his team gave up a late goal to the Flames, seemingly saying to his coach, “Do your job.”

I did try to find additional information on this without success. The Denver Post did not have a reporter on scene, instead goind with an AP game story, the Avs website posted Jared Bedner post-game, he did not address it and the Calgary newspapers had nothing on the incident.

The Avs lost the game 5-3.
