In Miami, Heat coach Erik Spoelstra changed James's role to a more unconventional one.[1] James spent more time in the post and improved his shot selection and accuracy on jump shots.[120][303] He also learned how to work as an off-ball cutter in the Heat's "pass-happy" offense.[304] Behind these improvements, James's overall scoring efficiency rose to historically great levels.[305] During this time, ESPN's Tom Haberstroh called James's free-throw shooting his biggest weakness, describing it as "average".[306] Upon returning to the Cavaliers, James began to experience subtle age-related declines in productivity,[307] posting his lowest scoring averages since his rookie season in 2015 and 2016.[7][308] His shooting also temporarily regressed, and he briefly ranked as the NBA's worst high-volume shooter from outside the paint.[309] Despite these changes, he remained an elite offensive player who beat defenses with body control, strength, and varying attacking speeds.[10]
