Trying to look at this from Oden's point of view, the one advantage we might have over teams like Atlanta and New Orleans is that we already have a young, offensively dominant big man in place.
Atlanta has Horford and New Orleans has Davis and both of those guys are more well-known for their defense and rebounding than their offense. Atlanta also just signed Millsap and drafted two 7 footers, one of whom opted to return to Spain rather than fight for minutes this season so that's a bit of a cloudy future there minutes-wise.
New Orleans looks like a well-balanced roster with a chance to win right away. That's certainly an appealing situation. I'd probably pick them too, but you do have to be thinking in the back of your mind somewhere that Oden/Davis isn't exactly a match made in heaven. They could be a dominating defensive front line or they could get in each other's way going for blocks and rebounds. They also project to have the vast majority of their offense coming from the back court until they find a consistent post scorer. Maybe not so well balanced after all.
Sacramento is still a long way from being competitive, but it's a low pressure situation right now with a great complimentary big man. If it does work out, that duo alone is going to make Sacramento an annual playoff team if you can keep them together. I don't think you could say that about any other team under consideration right now. The Spurs are going to be rebuilding when Duncan retires, same with Dallas and Dirk, and Miami can't afford to keep Oden anyway if he earns himself a real contract in the future. The again, would he even be thinking beyond this season right now?
