I stumbled upon an article by
Arturo on wagesofwins.com today:

What I really want to know is how much better or worse than the team average is the player’s defense based on opponent production

He used positional averages to evaluate the players worth on defense and he admits that this still isn't quite perfect, because it groups multiple players together. So I went with counterpart stats:
Code:
PlayerName oAdjPER oAdjWS48 oAdjWP48 oDiffPER oDiffWS48 oDiffWP48
Jason Kidd 12.11 0.117 0.196 -0.88 0.013 -0.027
Shawn Marion 16.00 0.087 0.172 0.58 -0.010 -0.016
Dirk Nowitzki 22.40 0.199 0.161 0.64 0.011 0.101
Rodrigue Beaubois 14.78 0.087 0.132 -1.14 -0.005 0.042
Delonte West 18.14 0.154 0.119 2.87 0.036 -0.028
Brendan Haywood 11.11 0.110 0.112 -2.38 -0.023 -0.060
Jason Terry 16.81 0.104 0.106 1.15 0.024 0.031
Vince Carter 16.19 0.154 0.099 3.23 0.060 0.022
Brandan Wright 16.68 0.120 0.074 -5.25 -0.085 -0.180
Ian Mahinmi 13.06 0.126 0.053 -0.89 -0.035 -0.078
Lamar Odom 8.04 -0.052 -0.073 -1.26 -0.048 -0.026
The
oAdj values are the opponent adjusted metrics,
oDiff specifies how much the player lost or gained on the metrics based on opposing production.
Pretty interesting stuff. Dirk, who is not valued by the WP48 metric very highly because he takes a ton of shots and rebounds pretty poorly, gets a nice bump in all metrics based on his defense. Meanwhile our centers take a huge hit, especially Wright.
Our top5 players according to the oAdjWP48-metric (which is considered the most accurate one) are Kidd, Marion, Dirk, Roddy and West.
