Impact rookies in the postseason

Boston's Tyler Seguin and Brad Marchand, both rookies in 2010-11, were integral to the Bruins' Stanley Cup run two years ago.

Seguin notched six points in the first two games of the Eastern Conference finals, and Marchand simply blew up in the entire postseason stretch, tallying 11 postseason goals -- including five in the Stanley Cup finals versus Vancouver -- and eight assists. Marchand also single-handedly turned the tide of the series in Game 3, forcing a turnover before splitting three Canucks defenders for a short-handed goal.

Last season, it was rookie Adam Henrique of the Devils providing the spark, scoring an overtime goal on Rangers goaltender Henrik Lundqvist in Game 6 of the Eastern Conference finals that sent New Jersey to the Cup finals. And let's not forget Dwight King of the Stanley Cup champion Los Angeles Kings, a youngster who had more goals (four) than the Coyotes (three) in the first three games of the Western Conference finals.

This season, the Ottawa Senators, who have a 3-1 game lead on the higher-seeded Montreal Canadiens, are flush with rookies making an impact.

Mika Zibanejad and Cory Conacher each had a key goal in Ottawa's overtime win Tuesday night, and forward Jean-Gabriel Pageau leads the team with three goals. But it is second-round pick Jakob Silfverberg who is chipping in vital two-way play.

Silfverberg has three points in four games, and the Senators have had possession of the puck 47.1 percent of the time when he is on the ice. That's not bad when you consider that almost two-thirds of his ice time in Games 1 and 2 (when Montreal had last change) came against the Canadiens' top pair of P.K. Subban and Andrei Markov. The young Swede also has logged time on special teams, including 1:50 on the penalty kill and 3:00 when the Sens have the man advantage.

Here's a look at seven other rookies who have been instrumental to their team's playoff fortunes so far in the 2013 Stanley Cup playoffs.
