For all of our offseason prognostication, NBA teams are still going to come out and surprise us when the 2013-14 season gets underway.
There's only so much we can learn from summer acquisitions and late-season trends. No team jells exactly how we expect them to to start a new season; whether the roster has changed significantly or very little, a year does make a difference, for better or worse.
A single individual can be the catalyst for a major change in a franchise, or a sweeping organizational change can fundamentally alter the on-court product. We can guess at where the transformations will occur, but we won't know what they are exactly until play begins again.
