Boy, was I wrong.
As a matter of fact, it was the other way around.
Washington's current three-game losing streak has been caused mainly by a defensive struggle. That is to say, their defense has been flat out blowing it for the team.
Two of Pittsburgh's game-winning goals have been caused by deflections off Washington's own defensemen. Both of these deflections occurred in overtime. Game Three's game-winning-goal, a slap shot off the stick of Penguins defenseman Kris Letang, ricocheted off Shaone Morrisonn's left knee and went past a helpless Simeon Varlamov. The clincher of Game Five bounced off a diving Tom Poti and into the net.
A little more D on both of those and we might be talking about the Capitals' gameplan for the Eastern Conference Finals.
There's been a few times where Varlamov has made a great stop on an odd-man rush, the puck is left in the slot by the Caps defensemen, who seem to think that the play stops after Varlamov makes a save, and a Penguin will get off a wide-open shot.
There's been a few times where two, sometimes three Caps defensemen will leave the slot wide open to go after the guy with the puck in the corner. A good pass and there's another wide-open shot.
Luckily for the Capitals, there's been two things keeping them in the playoffs: their offense, and rookie goaltender Simeon Varlamov. Without those two, Washington wouldn't even be in the Second Round, and the Penguins would be playing the Carolina Hurricanes instead.
