37. Terence Crawford
Crawford is one of the top boxers of his generation and a former pound-for-pound king. However, he suffered because his promoter Top Rank made life difficult for him. They affected his legacy because they refused to sanction a clash with his rival, Errol Spence Jr. Crawford refused to sign a new deal with the promotion but things became even more twisted.

Next Crawford sued them after accusing Bob Arum of racial bias. It was an extremely messy scenario that tarnished the sport of boxing. But Crawford felt justified because he alleged that they failed to represent him properly. It also brought the boxing promoters into focus because athletes realized that they had more power. Crawford sought over $10,0000000 in compensation (via Boxing Scene).
