3. Don King
King literally killed people. This definitely makes him one of the shadiest people on this list. The boxing promoter is one of the most notorious figures in the history of the sport. He exploited fighters like boxing was going out of fashion. King’s legal team is always busy. This is because they’ve faced so many lawsuits down through the years. Larry Holmes, Lennox Lewis, and Muhammad Ali all sued the promoter.

It all comes down to money because King sneakily attempted to underpay his fighters. Mike Tyson also sued him for millions of dollars and won the case against King. He also called him ‘vile’ and ‘greedy.’ Those words adequately sum up one of the shadiest figures in sports promotion. Historically, boxing has a terrible reputation but King is one of the worst offenders. It’s amazing he’s never spent time in jail.
