Special-teams play is one of the decisive factors in building a winning team in the National Hockey League.
The Los Angeles Kings ran through the majority of the playoffs despite having a nearly non-existent power play. However, after the Kings dropped two games in a row to the New Jersey Devils and seemed like they were in danger of blowing the series, they used three first-period power play goals in Game 6 to take charge of the game and ultimately win their first Stanley Cup.
In 2011, the Boston Bruins had to endure similar failures on the power play through much of the first three rounds of the playoffs. However, that unit came alive in the Stanley Cup Finals and that helped them dispatch the Vancouver Canucks in seven games and win their first title in 39 years.
So even teams that struggle on the power play need that unit to come alive at some point if they are going to win. Here's a look at five of the best power play performers who have been signed as free agents this summer.
