Calm your panties, guys. It's just a stat, no need to get all worked up. Obviously, it doesn't mean that Beverly is the third best point guard or DeMarre Carroll is the fourth best small forward. My guess would be that guys such as them are treated well by advanced stats and this isn't no exception. They play on line-ups that succeed and stick to their limitations - play great D and make open shots. It reminds me of a recent blog by Justin Kubatko on how Horace Grant was third in win shares this one season just because he shot with a high percentage, didn't turn the ball over and rebounded, basically, knocked down open shots, didn't do what he can't do and played on a great team.

oh and Nick Collison has been among the league leaders in net rating (OffRTG - DefRTG = Net Rating) for the whole year so it doesn't surprise me to see him so high. it only tells me that even though they claim that "the metric isolates the unique plus-minus impact of each NBA player by adjusting for the effects of each teammate, opposing player and coach", basketball is a game played 5-on-5 and you can't calculate each player's worth just by his advanced stats like in baseball. the level of your team and the role you play has a severe impact on your stats, even the advanced ones.
