Yes, it could be how you play defense too. If you're leaping and jumping to block on every possession both on-ball and from help, your bigs are going to be out of position for the rebound. I play defense by position and LT RS, with the occasional block attempt. My bigs are usually in the right place after the shot goes up.

If you're trying to swat everything with Mutumbo like a Geico commercial, he's going to have a harder time rebounding.

For what it's worth, the knock on real life David Lee is that he sometimes gives up on defending his man in order to get a head start on the rebound. If you're jumping a lot with him inside, he's not going to get his real life numbers either.
