Both conferences conduct the playoffs in the traditional bracket format. All rounds are best-of-seven series. Series are played in the 2–2–1–1–1 format, meaning the team with home-court advantage hosts games 1, 2, 5, and 7, while their opponent hosts games 3, 4, and 6, with games 5–7 being played if needed. Once the playoffs start, the bracket is fixed; teams are never "reseeded", unlike in the National Football League (NFL) where the strongest remaining teams face the weakest teams in subsequent rounds. This format has been used since 2014, after NBA team owners unanimously voted to change the format of the NBA finals from the 2–3–2 format on October 23, 2013.
