I think both would be nice options and could be fairly cheap. On rumors okafor could try for a buyout especially since they didn't take his next year option. Henzonja could be a little more costly, kings offered a player and a second rounder but that doesn't sound too bad. May have to wait for Dec 15th for moves though.
Edit. After seeing they declined options on next year, if we traded for them we'd lose the right to match if they do well. In this case I'm not offering a lot for either, still want them though.
