Offense

As an 18-year-old rookie, James led the Cavaliers in scoring. He holds numerous "youngest to" distinctions, including being the youngest player to score 30,000 career points. During his first stint in Cleveland, James was primarily used as an on-ball point forward, and although his shooting tendencies were perimeter-oriented, he established himself as one of the best slashers and finishers in basketball. His combination of speed, quickness, and size often created matchup problems for opposing teams because James was capable of blowing by larger defenders and overpowering smaller ones. These qualities became more apparent in transition, where he developed a reputation for grabbing defensive rebounds and then beating the defense downcourt for highlight reel baskets. Around this time, James was frequently criticized for not having a reliable jump shot or post game. Teams would try to exploit these weaknesses by giving him space in the half court and forcing him to settle for three-pointers and long two-pointers, a strategy famously used by Spurs coach Gregg Popovich in the 2007 Finals, where James converted on only 36 percent of his field goals in four games.

In Miami, Heat coach Erik Spoelstra changed James' role to a more unconventional one. James spent more time in the post and improved his shot selection and accuracy on jump shots. He also learned how to work as an off-ball cutter in the Heat's "pass-happy" offense. Behind these improvements, James' overall scoring efficiency rose to historically great levels. During this time, ESPN's Tom Haberstroh called James's free-throw shooting his biggest weakness, describing it as "average". Upon returning to the Cavaliers, James began to experience subtle age-related declines in productivity, posting his lowest scoring averages since his rookie season in 2015 and 2016. His shooting also temporarily regressed, and James briefly ranked as the NBA's worst high-volume shooter from outside the paint. Despite these changes, he remained an elite offensive player who beat defenses with body control, strength, and varying attacking speeds.

For most of his career, James has controlled the offense as the primary ball handler on his team. His playmaking ability is generally considered one of his premier skills, and some analysts rank him among the greatest passers in NBA history. By exploiting his size, vision, and the attention James garners from opposing defenses, he creates easy points for his teammates with accurate assists. James executes unconventional passes, including after leaving his feet and through defensive traffic. His uncanny tendency to find the open man has helped force NBA teams to incorporate some elements of zone into their schemes to better cover the weak side of the court and prevent James from passing to open shooters. Early in his career, James was criticized for overpassing in pressure situations, in particular for passing instead of shooting in the waning seconds of close games; however, as his career progressed, James' clutch performance was viewed more favorably.
