Roberto "Hands of Stone" Duran,full name Roberto Durán Samanieg in my opinion pound for pound in the top 5 of all time,one of only 2 boxers to fight in a span of 5 decades and won world titles in 4 different weight classes,matched up with Manny or Floyd in his prime would have beat them both easily,,possibly in the same night LOL,,,,,his personal life style,strife and mental demons were a hindrance but he still managed to construct one of the best and most impressive records in boxing history........in his first Leonard fight he did what no one had done before he (Duran) was past his prime and still beat the crap out of Leonard,in their second fight Leonard knew he wouldn't win fighting traditionally (like a man toe to toe) so he put on his tutu and danced the night away,a ploy Cassius Clay used in most of his fights,dancing and holding,,blah blah blah,,,, hate that kind of fight......Before moving up in weight classes as the light weight champion Duran amassed a 62 and 1 record,defending his title 12 times with 11 coming by knock out,,Durán gave up the Undisputed Lightweight Championship in February 1979.to move up in weight classes..................
