i'll be shocked if he leaves, regardless of how the season shakes out. more money, and it's really tough to make an argument that he'd be in a better situation going forward anywhere else. the teams that figure to have the cash and throw it at him are dallas, atlanta, and houston (i'm sure there are others, but i can't think of them off the top of my head).
dallas has dirk in a similar situation to kobe, except dirk's coming off knee surgery. if he signs there, it's him and dirk and...very little else. worse situation.
houston has harden and asik, who plays the same position as howard. dwight would eat up all their room, and you're stuck trying to win with lin, harden, asik, and minimums/mles. worse situation.
atlanta hinges on paul, who's staying in la. otherwise, it's horford, smith, and teague going forward. that's the best of these three, but still not better than:
kobe, nash, gasol (or his replacement in trade), mwp, followed by huge cap space and the most attractive market and franchise in basketball.
he'd have to really hate kobe, nash, dantonit, or the organization to turn down more money for any of those options, imo.
