Power plays will decide the Cup

The Chicago Blackhawks and Boston Bruins were two of the best even-strength teams during the regular season. The Blackhawks had possession of the puck 55 percent of the time, the third-highest percentage in the league, and Boston was a close fourth at 54 percent. They saw 61 and 55 percent of even-strength goals scored in their favor, respectively.

But as good as they have been when five-on-five, their power play units have not been able to get on track this postseason.

Whichever team can ignite its attack first could grab a significant advantage in the series, but which team has the best shot to score with the man advantage?
