Ron Artest and Jermaine O’Neal
Artest and O’Neal played together for the Indiana Pacers. Artest, also known as Metta World Peace, was one of the most enigmatic players in the league. There’s no denying his quality but he was also incredibly volatile as we saw during the notorious ‘Malice at the Palace’ brawl. He received an unprecedented suspension but the team supported him throughout.
Finally, Artest’s ban came to an end and he returned to basketball. But he immediately demanded a trade and this infuriated his teammates. O’Neal didn’t speak to Artest for 14 years because he thought that he was incredibly selfish. Later, it emerged that Artest had mental health problems but nobody knew at the time (via Basketball Network).
