Every 50-win season in NBA history in 1 chart

In honor of Tim Duncan's 15th 50-win season, we put together a chart showing how many such seasons each NBA franchise has in their individual histories. Surprise! The Lakers and Celtics have the most.

For franchises that relocated, we transferred their totals with the team with one exception, the Sonics. Because the Thunder are not the Sonics. This really just affected the Sixers (one 50-win season in Syracuse), Lakers (one 50-win season in Minneapolis), Pelicans (a handful in Charlotte), Wizards (a couple in Baltimore), Hawks (St. Louis) and Kings (one each in Cincinnati and Rochester).

The Rockets and Blazers could each still add one to their total this season. The Raptors could earn their first 50-win season in franchise history by winning out. A couple West teams have (very) outside chances of reaching 50.

The biggest lesson from this chart: being a fan of the Warriors, Clippers or Nets is typically an exercise in major frustration. Geez.
