29. Bob Arum
Arum is one of boxing’s oldest promoters and shadiest figures. The veteran Top Rank CEO attracted the attention of the FBI on numerous occasions because of potential match-fixing. This included Oscar De La Hoya’s fight against Shane Mosley. Other boxers were involved in this investigation and it was messy for Arum. He’s all about the money and doesn’t care about anything else.
He is one of the main reasons why Terence Crawford hasn’t fought Errol Spence Jr. Meanwhile, Arum has no issue working with alleged drug cartel boss Daniel Kinahan because “nobody was killed at my fights.” At the end of the day, the bottom line is the most important factor in Arum’s life. There’s no doubt about his success and his ruthlessness, but he also alienated himself from many top stars.
