40–20 rule
NBA rule on championships
From Wikipedia, the free encyclopedia
The 40–20 rule posits that a team in the National Basketball Association (NBA) must win 40 games before losing 20 to have a chance at winning that year's championship.[1][2] It was first publicized by 11-time NBA champion head coach Phil Jackson.[3][4] Since the NBA added the three-point line in the 1979–80 season, all champions won 40 games before losing 20, except for four teams: the 1994–95 Houston Rockets, 2003–04 Detroit Pistons, 2005–06 Miami Heat, and the 2020–21 Milwaukee Bucks.[5] The rule highlights how a team must be dominant over the first 60 games of the season to win a championship.[6]

Recent Developments
Since 2020, the 2019–20 Miami Heat, 2020–21 Milwaukee Bucks, 2021–2022 Boston Celtics, 2022–23 Heat, 2023–24 Dallas Mavericks, and 2024–25 Indiana Pacers have all made the Finals, despite not qualifying for the 40–20 rule. Although only the Bucks ended their campaign victorious, it is worth noting that, with load management, star players more likely to miss games in the modern NBA, making the rule potentially more difficult to achieve in the future.[7]
