He did. He was a cheater too - held excessive in almost every fight against decent fighters, and faked "low blows" in others. Probably the least talented HW beltholder of all time. Only his connections to King got this glorified clubfighter shot after undeserved shot at the WBA title. He was the poster-boy for boxing corruption in the 90s and early 2000s.
