The Washington Capitals have lost three straight games. Their offense has been anemic lately. But one aspect of their game has become infamous this season: the once vaunted power play. After being one of the league’s top units since the Bruce Boudreau days, the squad is ranked 22nd in the NHL this season, converting less than 15 percent of the time. In response, Caps fans have incessantly mocked and or panicked about the man-advantage. But head coach Barry Trotz has a solution: Jay Beagle. The center, 31, has never scored a regular-season power play goal in his nine year NHL career.
