One of the more surprising stories from Ottawa this season has been the potency of the Sens penalty kill's offence. Under head coach D.J. Smith this season (and more specifically assistant Jack Capuano who leads the team's PK unit), the Senators currently sit middle of the pack at 15th overall in penalty kill percentage (81.0%) but it's been the team's offence while shorthanded that has been a pleasant surprise.
The Senators lead the NHL in shorthanded goals (11) and have three forwards (Namestnikov, Pageau, Tierney) tied for tops this season with 3 SHGs apiece. Namestinkov, who was acquired from the New York Rangers earlier this season, is also tied for the most shorthanded points this season (3G, 2A - 5P).
The team's power play on the other hand has struggled for chunks of the year and is operating at just 14.4% efficiency to date but has shown big improvements recently. Through 10 games in January, the Senators have scored 8 of their 22 power play goals this season and are clicking at a lethal 28.6% this month.
