It would have depended on if Duran was in shape or not. He only had 2 good fights at 147, and looked just plain bad in the rest at welterweight. Floyd was only a 12 round boxer, but his best shot at Duran would have been 147 where Manos de Piedra does not rank amongst the best ever in that division. At 135, I like Duran but it would have been tougher than a lot of people out there think.
