Dwight Howard

Dwight Howard's three Defensive Player of the Year awards underscore his prime impact, but his legacy is a cautionary tale of wasted potential. He averaged 18.4 points and 12.9 rebounds in peak seasons, yet his post-game was limited to a predictable right-shoulder hook—shooting just 48.8% from the line in 2012-13, 12.4% worse than the average center's free-throw percentage. His locker-room toxicity cost him seven teams in eight years, a turnover rate that makes #2 Carmelo Anthony's team-hopping look stable by comparison. On-court, his refusal to set hard screens or roll effectively capped his offensive ceiling; the Lakers' net rating improved by 6.4 points when he sat during 2012-13, a swing 3.2 points larger than the typical star center's on-off split. A dominant body without the mind to match is overrated history.
