It's hard for NBA general managers to significantly upgrade their starting lineups, especially with a weak free-agent class to work with. And yet seven have still managed to do exactly that.
Most of the teams who have improved over the offseason have done so through the draft or by acquiring depth, but these seven squads have managed to fill up one of the five starting spots with a player stronger than the incumbent. Other teams have been able to upgrade single spots in the lineup, but corresponding declines negated any advantage they might have gained.
If your team is featured here, you're probably in good shape going into the 2013-14 campaign.
Three of the seven teams should be considered playoff locks, while another trio has improved enough that each of the members appears likely to advance to the postseason. Then there's one squad that improved, just not enough.

Note: Restricted free agents still expected to return to their old teams will be given asterisks.
