I know, I know, this is kind of the understatement of the century, but I hadn't realized just how terribly our offense has been since the trades until friend of the site Kevin Broom (TheSecretWeapon) sent me this graph. Broom's a former contributor to Real GM and a big figure in the NBA advanced stat community, and he sent me this chart he made graphing the Wizards' game-by-game offensive and defensive efficiency ratings.

The green line refers to our game-by-game offensive efficiency, and the orange dotted line is team's offensive rating trend line for the season. As you can see, it's gotten really, really ugly recently. The light blue line is the league average, and as you can see, we've been really, really far below that recently.
The silver lining is that our defense (red line) was doing well before this recent five-games-in-six-days stretch. Hopefully that at least gets back to a decent level. However, what these numbers clearly show is that, for all of Andray Blatche's success, you cannot build a good offense with him being your number one option. He needs help, and lots of it, which if fine but ultimately a reality we need to face.
