This. The Spurs, at least, recognize what they are and focus on what they do well. The majority of NBA franchises(large market or not) shoot for the moon, miss terribly, and then don't have any other plan in place and are forced to scramble. Even the ones that do hit the target tend to rest on their laurels more often than not, content that merely landing the star is enough. You could argue even the Spurs weren't immune to this during some of the Duncan years, but that they realized it, adjusted, and contended late in his career is pretty impressive in and of itself.
