All great boxing matches are built around a personal rivalry. It's therefore a great shame that Bob Arum and rival boxing promoter Don King have never got in the ring to settle the score; the two premier names in the world of fight promotion have been at each other's throats for most of the past fifty years.
Arum used to work for the Department of Justice, and only became interested in boxing when he was assigned by the Government to confiscate profits from a Sonny Liston vs Floyd Patterson match in 1962. Stunned by the amount of money that a big fight could generate, Arum chose to get involved, founding Top Rank, a promotion company that would go on to shape much of the way boxing has been promoted in the years since. He's worked with everyone from Muhammad Ali to Floyd Mayweather, but has often been a controversial figure, admitting in court that he once bribed the IBF to boost the ranking of one of his fighters.
