The greatest middleweight of all time vs Hopkins. Hagler, would no question press the fight and win on the cards, clearly. iT would not be that close.
Hopkins would win. Hagler could not bully him and would be giving up certain physical attributes that he had over many of his middleweight foes.
At 160 I think Marvin wins by a UD. BHop was slick and tough, but Marvelous Marvin had greater weaponry at his disposal... He throws too many timed hurtful punches and in his prime (80-82) would be too much for a more paced Hopkins.
Hopkins for sure. Just too smart and haglar ain't nearly quick enough to give him problems like some faster fighters have
