In which NBA Finals series did LeBron James average a triple-double?

LeBron James averaged a triple-double in the 2017 NBA Finals. Playing for the Cleveland Cavaliers against the Golden State Warriors, he averaged 33.6 points, 12.0 rebounds, and 10.0 assists across the five-game series.

That performance made James the first player in NBA history to average a triple-double in an entire Finals series. A triple-double means reaching double figures in three statistical categories; in this case, James combined scoring, rebounding, and assists at extraordinary levels over multiple games rather than in just one contest.

The Cavaliers lost the series 4–1, but James still produced one of the greatest individual Finals performances ever. He recorded a triple-double in Game 4 with 31 points, 10 rebounds, and 11 assists, while the series also included a 41-point, 13-rebound performance in the deciding Game 5.

The 2017 Finals are also remembered for the Warriors' 16–1 postseason record and Kevin Durant's first championship with Golden State. James's statistical achievement remains distinct: no other player had previously averaged a triple-double across a complete NBA Finals series.
