8. Kevin Durant vs. Draymond Green
About halfway through the 2018/19 season, Durant announced he was leaving the Golden State Warriors. Nobody expected the on-court feud that erupted between him and Green in a game against the LA Clippers. Green came off worse because his team suspended him for his actions.

He confronted Durant after losing the ball and questioned him over his free agency. Green also called Durant a b**ch several times and the argument simmered over into the locker room. To rub salt into their wounds, Golden State lost to the Clippers in overtime. Durant ultimately signed with the Brooklyn Nets.
