Top 30 best NBA season turnarounds

This list shows the number of additional victories that each NBA won compared to the previous season. The teams are shown with their current city and name, along with the season when they achieved this feat. The 1999-2000 season is an unfair comparison because there was a lockout the previous year that led to only a 50 game season, as compared to the regular 82 games. Eight of the records on this list are due to that change.
