There is no question as to who would win that fight, Roberto Duran. I watched him hunt down Vilomar Fernandez for fourteen rounds while Fernandez used every trick in boxing to keep Duran from hitting him and suddenly Duran came out of nowhere and splat, down went Fernandez. People in boxing also forget that Duran was a bomber but he had superior boxing skills as Dejesus found out in bout number two with Duran. Ken Buchanan was a speedy fighter and Duran mugged him in the late rounds skill and power. I saw that one too. Pernell is a great boxer but Duran had all the skills and a punch to go with it at lightweight, Duran was also a Welterweight , Jr. middleweight and middleweight champ, no question as to who would win.
