grant hill was certainly a medical success story, considering the persistent ankle problem he had to deal with, on top of other nagging injuries, but the fact remains that he's a perimeter player. i'd be much, much more leery of a seven-footer who had major surgery on both of his knees by the age of 21. greg oden's a low-block guy, meant to anchor a defense, and will take serious punishment in the paint as a result. can his body handle it? the chances of oden successfully returning to the game of basketball are not exactly in the same league as grant hill's success story in returning to the game of basketball...
again, i agree that there's not much risk in a cheap, short-term, heavily-insured contract, but i'm also not sure what the point is. it'd be one thing if greg oden had been among the best young centers in the league prior to scrubbing out. unfortunately, he wasn't. he showed a few flashes of potential greatness before his second knee injury. in limited minutes, and across a small sample size of 21 games in 2009, he was rebounding well, and he was starting to establish a defensive presence down low, while hitting a high percentage of shots at the rim. but he wasn't dominant. "potential" was still the operative word...
and now that his body has failed him, i don't really understand what a team would expect of him heading into the '13-'14, three-and-a-half years since he last played in an nba game. he was a developing player before three micro-fracture surgeries doomed his career. he wouldn't be returning to the game as an established talent. even on a cheap contract, he's a major rehabilitation project, and there are other young tall guys out there with defensive potential that you can "take a flier on" who don't also run the risk of collapsing in a heap during their first minutes of nba action...
everybody wants to hope that greg oden can still play in the nba, because he seems like a nice guy, and it's just terrible luck that he hasn't been able to stay on the court. but personally, i think he's a lost cause in a contemporary nba that moves really fast. unless a team intends to sign him for garbage minutes and/or developmental league action, i don't expect he'll stick anywhere...
