What Happened to NBA Anti-Tanking Rules?

The concept of 'tanking' in the NBA, where teams intentionally underperform to gain a higher draft pick, has been a persistent challenge for the league, leading to numerous adjustments to its draft lottery system over the decades. Initially, the NBA introduced a lottery in 1985 to prevent the worst team from automatically getting the first pick, a system that gave all non-playoff teams equal odds for the top selection. This evolved into a weighted lottery system in 1990, and further in 1993, to give teams with worse records a progressively higher chance at the top picks.

Despite these changes, the early 2010s saw the rise of 'The Process' by the Philadelphia 76ers, a highly publicized multi-year rebuild involving intentional losing to accumulate high draft capital. This strategy, while eventually yielding star talent, drew significant criticism for its impact on competitive integrity and fan engagement. In response, the NBA Board of Governors approved a major lottery reform in 2017, which became effective for the 2019 NBA Draft. These changes flattened the odds, giving the three worst teams an equal 14% chance of winning the No. 1 pick, down from 25% for the worst team previously. The goal was to disincentivize teams from being the absolute worst.

However, by the 2025-2026 season, Commissioner Adam Silver and the league observed a resurgence, and even an intensification, of tanking, with multiple teams seemingly vying for better draft positioning in a perceived deep 2026 draft class. Silver publicly expressed strong dissatisfaction, vowing to implement 'substantial changes' to 'fix' the issue. This led to months of discussions among the Board of Governors, competition committee, and general managers, exploring various proposals, including concepts like a two-year record for lottery odds or an 18-team lottery with flat odds.

A pivotal turning point came with the emergence of the '3-2-1 lottery' proposal in April 2026, which gained significant traction. This system proposed expanding the lottery to 16 teams (including Play-In participants), assigning different 'lottery balls' (3, 2, or 1) based on standing, and crucially, creating a 'relegation zone' where the three worst teams would have fewer lottery balls (5.4% chance at No. 1) than teams ranked 4th through 10th worst (8.1% chance). It also included unprecedented restrictions: no team could win the No. 1 pick in consecutive years or secure three consecutive top-five picks. Furthermore, the commissioner's office would gain expanded disciplinary authority, including the power to alter lottery odds or change draft positions for teams found to be tanking.

As of May 28, 2026, the NBA Board of Governors officially approved these comprehensive anti-tanking measures. The new rules are set to be implemented for the 2027 NBA Draft and will remain in place through at least 2029, with a potential re-evaluation for 2030, possibly considering a 'draft credit' system. While the league aims to eliminate blatant tanking and incentivize winning throughout the season, some analysts express concerns that these changes might merely shift the incentives for tanking to different tiers of teams or disproportionately penalize genuinely struggling franchises.
