I like Carter in this one. Graziano was not hard to hit, and Rubin is underrated as a defensive fighter. Carter by ko in 6 or less.
Two guys who could melt ANYONE if they landed square. But Ruben has a better chin even if Graziano might hit a shade harder. And Carter was a full blooded middleweight and Rocky was a little small for 160 even if he was very strong. I think Carter boxes smarter too and that adds up for the Hurricaine.
