This bout is a case study in strength, of WILL and BODY.

Hagler is relentless and demonstrates a predatory appreciation for the dynamics of shifting leads. Hagler could fight from either side, the hardest working middleweight in history. Hagler had the most dangerous collection of opponents of any champion. To see how dangerous he was against a man who could not hit like a heavyweight, see his highlight reel below. Note his lunging right jabs, including a lunging up jab, with devastating power.

Marvin Hagler was a punching machine.
