He posted basically the same numbers his two years in Dallas as well. One of those years Jason Kidd out rebounded him....
Brandon Bass in his third and fourth years in the NBA (first two being seriously used), getting out-rebounded by basically the best rebounding PG in the league, but only on DRs (Bass smoked him on ORs). I'm OK with this.
He's played minutes for top defensive rebounding teams his four years of being a rotation player, so he certainly could see a bump playing for the C's but the diminshing returns on defensive rebounding isn't big enough for him to suddenly become a strong rebounder.
I think it's way too premature to be coming to conclusions, here. We're only a few games into a new team for him. Rebounding is not FT%, where it's just you and the basket. The team's defensive system and positioning (how many rebs does he get if he's roaming the perimeter?), relative strength of other team rebounders on the floor, etc, all factors into his performance by the numbers.
I see the effort that the guy plays with, the height he jumps, and the way that he tears down the rebounds he DOES get, and while that's no predictor of future performance, it means that this soldier wouldn't be surprised if he did well with us. I'm willing to believe that being around elite rebounders had an impact on his numbers prior to coming here.
Although I don't know that everything is gravy for his stats now that he's here. My favorite line-up with Bass is when KG slides to the 5, and other than Ray, there are a lot of good rebounders for their position in that line-up.
