James Harden
Harden is one of the most polarizing NBA players today. There’s no denying the 10-time All-Star’s skills because he is an outstanding player. But some people question the former MVP’s motivation and commitment. The Houston Rockets resented him because he forced his way out from the team. But the most interesting of his long-term dramas involved Kevin Durant.

The pair became teammates when the Nets tried to assemble a super team. Allegedly, Harden didn’t like Brooklyn’s playing style and resented Kyrie Irving. He stopped giving maximum effort and this infuriated Durant. In the end, Durant signed off on Harden’s move to Philadelphia because he didn’t think it was working (via Essentially Sports).
