An odd thread, taking GGG at 35 vs. Duran at his best at middle. I'd pick GGG. Styles favor GGG, and GGG has a top level jab if a boxing match somehow happened. Duran gets way too much credit for going the distance with Hagler, who looked apprehensive and afraid at times to open up, but won by a larger margin than what the judge's scorecards said.
Fair enough ....but i dont actually see ggg as a big middleweight in this day and age....he stays in shape all year round abd probly comes in 166-168 on fight nite as opposed to a jacobs who looked 180 in his battle v ggg...ggg is very strong and a power puncher and on fight night duran may only be 162 assuming he comes in 156....so yes there is a size difference...but not that much
