Washington has seen a consistent drop as well over the years, having drawn the fourth-lowest power plays in the league this season with just 217 opportunities in 72 games.
Forwards Mike Knuble and Brooks Laich feel playing a more conservative style under Coach Dale Hunter might be contributing to the lack of power play opportunities, and they may be right.
Since the team abandoned the run-and-gun offense that was so successful during the 2009-10 regular season, they have been drawing fewer restraining fouls, which include hooking, holding, tripping and non-goaltender interference.
The decline in restraining penalties drawn per game becomes more pronounced when you look at this season's split under the two coaches.
However, the reduced opportunities are not the result of drawing fewer holding and hooking penalties as Laich suspected, but instead because they are drawing fewer tripping penalties.
One way to get more power-play opportunities is to possess the puck more, and that starts with moving the puck into the offensive zone. If the Capitals can generate more offensive-zone time utilizing Hunter's conservative system, not only will that allow them to create more scoring chances, they might be able to produce another power play per game as well.
