Metta World Peace
Ron Artest was a lunatic but that’s also why people loved him. He was a maniac on the court as well as one of the most irreverent trash-talkers ever. James Harden felt the full brunt of Artest’s ruthless nature after the latter refused to shake his hand. “I don’t shake substitute’s hands,” the polarizing star said (via Insider).

Harden went on to become one of the top players of his era but this was a chastening moment. Meanwhile, Metta went after the likes of Paul Pierce and Kobe Bryant without remorse. This didn’t always work but he didn’t care because that’s the type of person he was. Every team needs a good trash-talker and Artest eagerly accepted this role.
