LeBron James
2016–2018: End of second stint in Cleveland

The 2016–17 season was marred by injuries and unexpected losses for the Cavaliers; James later described it as one of the "strangest" years of his career. Following a January defeat to the New Orleans Pelicans, James publicly criticized Cleveland's front office for constructing a team that he felt was too "top heavy", for which he received countercriticism. The Cavaliers finished the season as the East's second seed, with James averaging 26.4 points and career highs in rebounds (8.6), assists (8.7), and turnovers (4.1) per game. In Game 3 of the first round of the playoffs, he registered 41 points, 13 rebounds, and 12 assists against the Indiana Pacers, leading Cleveland to a comeback victory after trailing by 25 points at halftime, representing the largest halftime deficit overcome in NBA playoff history. In Game 5 of the Eastern Conference Finals against the Boston Celtics, James scored 35 points and surpassed Michael Jordan as the league's all-time postseason scoring leader. The Cavaliers won the game and the series, advancing to the NBA Finals for the third consecutive time against the Golden State Warriors, who had signed James' rival Kevin Durant during the off-season. Behind averages of 33.6 points, 12.0 rebounds, and 10.0 assists per game, James became the first player to average a triple-double in the Finals, but Cleveland was defeated in five games.

Prior to the start of the 2017–18 season, the Cavaliers overhauled their roster by trading Kyrie Irving to the Boston Celtics, who requested a trade in part because he no longer wanted to play with James. After a slow start to the year, Cleveland rebounded by winning 18 of 19 games in December. Their turnaround began with a victory over the Wizards on November 3 where James scored 57 points, which represented the second-highest point total of his career and tied a franchise record. In January, the Cavaliers had a losing record, and James was criticized for his lackluster effort. The next month, James won his third All-Star Game MVP Award, after posting 29 points, 10 rebounds, eight assists, and several key plays to help Team LeBron win over Team Curry. Following another round of trades in February, Cleveland returned to form and James reached a number of historical milestones; on March 30, he set an NBA record with 867 straight games scoring in double digits. James eventually finished the season with averages of 27.5 points, 8.6 rebounds, 9.2 assists, and 4.2 turnovers per game.

In the playoffs, James guided the Cavaliers to another Finals rematch with the Golden State Warriors. Along the way, he had some of the most memorable moments of his career, including a game-winning shot against the Pacers and another against the Raptors, after which a new nickname, "LeBronto" was popularized. In Game 1 of the NBA Finals, James scored a playoff career-high 51 points, but Cleveland lost 124–114 in overtime. Following the loss, James injured his hand after punching a wall in the locker room, which hindered his effectiveness for the remainder of the series. The Cavaliers lost the series in four games, with James averaging 34 points, 8.5 rebounds, and 10.0 assists per game for the Finals.
