duran's defense at 135 was light years ahead of chavez and duran typically only struggled with tricksters. chavez was not slick. Against opponents that came at him, duran would slip and duck their attacks and counter them all to ****. He'd work chavez's head and body all night and though JCC would have his moments, he'd been outboxed and outworked to a UD.
One of my top 5 fav mythical fights. Duran by close decision I think, natural size & punch power being the difference.
