Title: President, Don King Productions
Pro: Still the most recognizable face (and hair) in boxing; promoted some of Muhammad Ali's most memorable bouts, like the "Thrilla in Manila" and "Rumble in the Jungle."
Con: Served 3½ years in prison for second-degree murder, though a judge reduced the conviction to manslaughter, in the late '60s. Under King's de facto control, boxing has sunk into irrelevance.
