Have you ever heard of the concept of number-space rebounding? A one-space rebounder is someone who will only get rebounds that fall into his immediate area. Hence, that one space. Two-space rebounders are rebounders that can grab rebounds in positions where they start off, plus the space that would be occupied by another player standing next to him. The scale adjusts up to five spaces, as a player who can secure rebounds at spaces five player-spaces away from him are elite rebounders. Knowledgeable basketball analysts (Jeff Van Gundy, Charley Rosen) proclaim that Rodman was a five-space rebounder and the best rebounder of all-time, at least since Wilt and Russell. Dwight Howard is regarded as a four-space rebounder as he can get to balls few others can, plus is so massive that he won't miss rebounds in his area. Shaq, in his prime, was a two-space rebounder who got the majority of his boards simply be being big and strong. There's nothing wrong with that, but Shaq had, and has limited rebounding range while Howard's range is off the charts. Calling Shaq a better rebounder than Howard is just flat-out wrong.
