NBA Weighing Rule Changes To Discourage Tanking

The NBA, in the hopes of further discouraging teams from tanking, has begun soliciting input from team owners and general managers on possible rule changes, reports ESPN’s Shams Charania. According to Charania, the league sought feedback on a number of ideas at a Board of Governors meeting last Friday, including:

1. Eliminating mid-lottery protections on traded picks, so that traded picks could only include either top-four protection or top-14 (or higher) protection.
2. Prohibiting teams from drafting in the top four in back-to-back years.
3. Locking lottery positions as of March 1.

As Charania explains, the NBA is looking for ways to discourage teams from “deliberately manipulating” their rosters in an effort to land a higher draft pick or hang onto a protected pick. The league’s goal, Charania says, isn’t to stop young, rebuilding teams from using their normal rotations, but to reduce instances of clubs sitting regular starters and encourage them to remain competitive down the stretch.

Some of the most egregious instances of tanking in recent years have involved teams looking to retain control of traded picks with protections on them. Charania points to the 2023 Mavericks, who owed the Knicks their top-10 protected first-rounder and held out key players in the final games of the season in order to hang onto that pick despite still being in contention for a play-in spot. The first proposed rule described above would be designed to target those cases.

The second proposal would have had an impact on multiple recent drafts if it had been in effect. For instance, the Rockets and Spurs, two of the Western Conference’s most promising up-and-coming teams, drafted in the top four in several consecutive seasons — Houston selected Jalen Green (2021), Jabari Smith Jr. (2022), Amen Thompson (2023), and Reed Sheppard (2024) with top-four picks, while San Antonio did the same with Victor Wembanyama (2023), Stephon Castle (2024), and Dylan Harper (2025).

The third proposal would disincentivize post-March 1 tanking, but wouldn’t necessarily eliminate instances of teams tanking prior to that date.

The NBA is focused on tanking in part because gamblers have allegedly been able to access inside information about lottery-bound teams sitting certain players in recent seasons, Charania notes. Federal investigators say that an unnamed co-conspirator, who matches the description of Trail Blazers head coach Chauncey Billups, told a bettor that several Portland players would miss a game in March 2023 as the team began to tank.

In the wake of that federal probe into illegal gambling that resulted in the arrests of Billups, Heat guard Terry Rozier, and former player and coach Damon Jones, the NBA is attempting to close off avenues for bettors to gain access to and use inside information. The league sent out a memo to teams last week detailing adjustments to the injury reporting process and proposed changes affecting prop bets.

No rule changes aimed at tanking have been approved at this point, but the subject figures to be an ongoing topic of discussion at upcoming Board of Governors meetings.
