Ron Artest
Artest played a central role in one of the most infamous NBA brawls ever. This controversial athlete went head to head with Ben Wallace before confronting a fan. Soon one of the most chaotic events ever happened and the NBA threw the book at everybody involved (via The Guardian).

Artest received one of the longest suspensions in history but the drama wasn’t over. The Pacers stuck by him throughout the controversy but he immediately demanded a trade when the ban ended. This was a betrayal but the seedy superstar didn’t care and he changed his name to “Metta World Peace.”
