arguello was monsterous at 130-35, he would present more problems then leonnard, but in the end duran would prevail
IMO this would have been a close fight till the end. you cant compare duran with the Hawk cuz IMO the hawk would have beaten Duran and Leonard if they fought him. Alexis' performace against the hawk above his best weight makes me think that he would have given duran fits at 135 but i will favor duran being the greatest 135 of all time.
How would Arguello present more problems than Leonard? Even Arguello's power is probably less than the naturally larger Leonard.
