11. LeBron James vs. Kyrie Irving
This one was a bit of a surprise. In one sentence, James just had no patience for Irving. After returning to the Cavaliers in 2014, he clashed with his teammate because of Irving’s attitude. When you’re totally focused on winning it’s difficult to respect somebody who doesn’t take the sport as seriously as you.

He felt that Irving was more concerned about his own statistics than those of the overall team. Eventually, Irving matured. But his relationship with James was nonexistent and he wanted out of Cleveland. Finally, he demanded a move and ended up moving to be the ‘man’ with the Boston Celtics.
