36. Kyrie Irving
Irving became a controversial figure when he departed the Boston Celtics for Brooklyn. This made it clear that he was chasing the money. However, he became even more notorious in 2021 when he refused to play for the Nets (via Sports Illustrated).

Technically, he didn’t want to get a vaccine during the global health crisis. New York State made this a mandatory requirement for professional athletes but Irving resisted. He threatened to leave his teammates high and dry. In the end, he followed through and upset a lot of people in the process.
