In the playoffs, the Cavaliers swept the Detroit Pistons in the First Round in four games, swept the Atlanta Hawks in the Semifinals in four games, before losing to the Orlando Magic in the conference finals in six games, despite the Cavaliers being heavily favored to beat the Magic.[2] The Magic would go on to lose to the Los Angeles Lakers in the NBA Finals in five games. Prior to their elimination by the Magic, many had expected the Cavs to appear in the Finals, which would've also been LeBron and Kobe Bryant's first head-to-head meeting in the NBA Finals.
This was the last time that James lost in the conference finals until 2023 when the Lakers were swept by the Denver Nuggets in four games.
