He made it look easy for the most part too. Subtle movement, dodge a shot here, duck a shot there, land a two piece repeat.
I don't know how many people realize what it means to be able to do stuff like this at 48 years of age. 12 full rounds against a guy 17 years younger who typically throws thousand punches a fight. All the little subtle things Hopkins does to cut that work rate in half and out land the younger man while throwing less punches. Legendary stuff.
