What's your budget? KChape25's suggestion of Horford is a pretty good one in the sense that Horford is very good at mid-range shots and also a quite good rebounder, though only adequate at defense. Big issue with Horford is his oddball slow-slow-slow-slow-FAST release.

Cousins might be a better option for economical with good midrange and rebounding and adequate defense. Or Marc Gasol for midrange and defense, but adequate rebounding. Parish for good but not excellent in all three attributes.

Or for Defense and Rebounding but poor shooting, then Dikembe.

And if you have a lot to spend, then Ewing, Robinson, or Hakeem...
