I believe it goes the distance in a war. Work rate will make the difference and I think Marvin may have that edge. To some degree GGG with his jab outboxes but this should be a hell of a war. Hagler 7-5
Really good post. Agree completely that Hagler was a boxer that could brawl when he thought appropriate more than a brawler that had some boxing ability when pressed (which seems to be the consensus around her e).
What a fight that would be. Woohoo! I'll go with Golovkin on boxing ability and comparable everything else.
