Mason Ginsberg did a fantastic job of breaking down the rates and showing what was good, what was poor, etc.

As you can see, Anderson, Gordon, Smith, and Lopez have poor rebounding rates for their position and Shabazz's rate would even be poor for a shooting guard, let alone a small forward.
Numbers dont tell the whole story, but they clearly point to all of these guys being bad rebounders and I think even the eye test tells us all that. Leaving Davis, and maybe Vasquez, as the only above average rebounders in the rotation could be a recipe for disaster.
Meanwhile, Otto Porter's rebound rate is similar to Aminu, which is the best on the team, and he also can hit the mid-range jumper and block shots. Shabazz is the better player, no doubt, but Porter would be a good consolation prize and might actually be a better fit. Chad Ford uses Pippen as the ceiling for Porter. Uh, yes please.
