Out of Shape
It’s a bare minimum for professional athletes to keep themselves in shape. However, Harden hasn’t always been good at doing this and this caused problems in Philadelphia. His fitness issues created a rift between himself and Kevin Durant who expected better from his teammate.
Allegedly, Durant even told Harden about his concerns but Harden didn’t want to hear it. It’s not the first time that he had weight problems because he reportedly stopped training when he forced his Houston exit. Harden ruined it for himself because he didn’t do his job properly (via Sports Illustrated).
