Keane was one of the most dominant midfielders of his generation. The Irishman played a crucial role in helping his country qualify for the 2002 World Cup. However, he played a central role in one of the most notorious bust-ups in soccer history (via Mirror).
The Manchester United star stormed out of their camp in Saipan. He left his teammates high and dry because he thought the organization was unprofessional.
Harden was the Rockets’ most important player. They built the team around his style and bowed to his wishes. Then he threw it all back in their face when he announced that he wanted to leave. This rocked the NBA.
He joined the Nets when they tried to buy a super team, but didn’t stay there for long. Finally, he ended up in Philadelphia and underperformed. It’s been a strange couple of seasons for Harden since he left his teammates high and dry (via Forbes).
In 2021, Watson became one of the most notorious figures in the NFL. The Texans suspended him for the entire season after sexual misconduct allegations emerged. But this came after Watson demanded a trade and threatened to leave the franchise hanging (via New York Post).
To be fair, Houston didn’t do themselves any favors by trading DeAndre Hopkins and J.J. Watt before this. Watson believed that they were too dysfunctional to compete with the top teams in the AFC. In the end, the Cleveland Browns swooped in and offered him a foolish NFL-record contract.
