Here are the team stats -- on court/off court differences -- for defensive rebounding while each of the big men are in the game:
(1) Perkins = +4.66%
(2) Garnett = +4.48%
(3) Davis = -0.90%
(4) Scalabrine = -0.55 (includes small portion of minutes at SF)
(5) Sheed = -4.09
(6) Shelden = -6.58%
These statistics aren't perfect by any measure but I do think they point in the right direction in this case.
If you watch closely when Shelden gets a shot at playing time you'll see him fail to keep his man off the glass on several occasions and it regularly costs the team some defensive rebounds.
OK cool. I thought he was brought in for rebounding. Do those stats mean that the team is rebounding badly or Shelden is rebounding badly? Because his DRB% is 21.5% (third on the team behind KG - 25.4% and Perkins - 24.7%.Sheed =18.4%, Baby =12.1%), which would suggest he is getting most of the defensive boards.
TP for the stats though.

It can mean either.
I think Shelden's individual rebounding numbers are misleading (rebounds per game, per minute and rebounding rate). Sorry, I mean his defensive rebounding is misleading. I think his offensive rebounding is very good. I think Shelden does a very good job at grabbing the rebounds but a very poor job of keeping his opponent off the glass which negates a lot of his value as a defensive rebounder.
I don't think the difference is as pronounced as those statistics indicate. I agree with
Meadowlark_Scal that Shelden's numbers would improve if given more minutes.
However, I do think the stats point us in the right direction ... and that is that while Shelden does a good job grabbing the ball the team generally does worse on the defensive backboards while he is in the game and I believe his inability to keep his man off the glass plays a large role in that.
So while I'd expect the stats to improve I would still expect him to have a negative defensive rebounding differential.
I think Perk + Garnett + Scal + BBD all do a good-to-very good-to-excellent job at keeping opponents off the glass while Shelden + Sheed are poor-to-very poor.
I don't think so. I think most of his good work at grabbing defensive rebounds is offset by his inability to keep opponents off the glass.
I think his offensive rebounding is his real strength on the backboards.
Just to go back to what I said earlier on in the thread -- I think Shelden adds a lot of value with his offensive rebounding but not much value with his defensive rebounding.
With the reason being his failure to keep opponents off the glass.
