The Colorado Avalanche have one of the best lines in hockey, but they're in the midst of a rough stretch that has seen them go 2-6-2 over their last 10 games.

The latest loss came Wednesday in the second night of a back-to-back on the road in Calgary.  The Flames topped the Avalanche 5-3 despite Colorado outshooting Calgary 35-16.  Late in the loss after the Flames' empty net goal sealed the win, frustrations boiled over on the bench between Nathan MacKinnon and head coach Jared Bednar.

Rough stretches like the one the Avs are currently enduring can bring out a lot of frustration from players and coaches.  At the end of the day, both MacKinnon and Bednar want nothing more than to win, so you have to imagine the frustration is coming from a good place.

That said, dominating games like they have in their last two against two of the top teams in the NHL isn't good enough and until Colorado strings together a few wins, the tension will be ever present.
