I'm really disappointed about his decision, 'cause he could have been a big hope for the years after the Duncan era.
That said, I also think that this choice was the worst for him, career oriented.
In S.A he would have been treated like a precious investment for the future, would have been taken care off for every thing and could have become better learning the offensive game from the best possible guy (and God knows if Oden needs to train his offensive game...expecially after three non playing years).
In Miami he instantly become the best option at center from day 1...so, despite all the insurances he received from whoever, he's at a big risk not to be taken care enough.
Imho, Spurs (with a crowded center position consisting in Tim, Splitter, Baynes and Pendergraph all able to play the role) in their current situation, could have given Oden a one year completely dedicated to his on court reabilitation and game improvement (wonderful training environment for a big).
Miami has the highest expectations possible of all the teams involved in his sweeptakes...and ther's no worst situation than this for an injured player just coming back to action 'cause, at the end, if your team needs you, you're supposed to play, despite your risky phisical conditions.
And I don't think that Greg is going to learn something from training neither with Anderson, Anthony or Haslem (all of them rely on defensive and athletic skills) nor from Bosh (totally diferent kind of player).
Imho dumb decision and horrible advise and counseling from his part.
For the Spurs, in any case, a big disappointment, but maybe a blessing in desguise.
First 'cause push our trainers to focus and give time to the improvement of promising players we already have at that position.
Second, 'cause this kind of decision seems to speak from itself about the player willingness to follow the obviously better path...for achiving results, you have to sacrifice your immediate expectations and work on yourself in the rifgt way. That's our culture. Oden, despite been, probably, a wonderful and kind guy, is still following the syrens....
