Give NJ the opportunity to see if he has healed up before offering him a big contract.
They will still have his rights when he's done over there, right? Because if not, then NJ has probably seen the last of him. Either he proves he hasn't recovered from his injury and doesn't get many (if any) offers back here, or he revives his career and has at least a half dozen NBA teams going hard after him.
I still believe that Shawn Williams will beecome a legitimate NBA player soon. Maybe they won't have to wait too long to get over what could have been with Nenad.
