3 takeaways from the Chicago Blackhawks' surprising upset of the Colorado Avalanche

Petr Mrazek was a wall in goal.

If the Chicago Blackhawks have any hope of winning this season, they need Mrazek to stand on his head. He did just that when he turned away 35 of 37 shots.

Colorado's two goals came on the power play scored by Valeri Nichushkin. He was one of three players coming in on a hot streak, so it is hard to get on Mrazek for allowing two goals to Nichushkin.

It looked like the Avs would cruise to an easy victory after going up 2-1. Then Reichel scored the equalizer and Mrazek settled down.

The power play came through.

It was not a great night for the penalty kill, but the Hawks' power play produced the game-winning goal. One of the league's worst scoring units on the man advantage found a way to win the game in the third period. The unit did it early in the power play when Tyler Johnson found the back of the net.

Scoring early was impressive considering the power play first's unit could barely muster getting the puck into the offensive zone during a second-period man advantage set.

With Seth Jones and Kevin Korchinski out, Richardson has had trouble finding someone capable of quarterbacking the unit. He has tried Zaitsev who came through this time. Normally, on the power play, he has looked like a player who spends more time as a healthy scratch. Shoot, Richardson had to put out five forwards at one point against the Vancouver Canucks last weekend.

This combination found a way to score the winning goal and the Hawks picked up an unlikely two points in the standings.
