From everything I've ever heard Moon was a absolutely massive super fly and fought at or around 118 plenty of times. Looking at his reach and height, he seemed to be be roughly the same size or a little larger then the likes of Rafael Herrera and Chucho Castillo, to name two fighters that I was thinking about him battling. How does Moon do if he spent his prime at 118 in the early 1970's? Just imagine the wars! Also I have some amateur footage of Moon that I was looking to share with anyone interested. Not going to put it on Youtube as it's been copyright struck before and I don't want to get banned. The matches are Moon against Gundhi Dass Kamble from the Asian games, Surarikul from the 1986 Asian games and Waturu Yamada from the same event.
Moon vs Shannon was a one of the greatest amateur bouts. I want found his fight in World Championship 1986 in U.S against Arnaldo Mesa.
Moon was a brilliant, heavy-handed exponent who wins plenty of fights at the Forum but also loses a few due to his propensity to bleed. He reached the Olympic quarter-finals in Los Angeles in 1984, stopping America's Robert Shannon and our own John Hyland when his eyebrows let him down against Pedro Nolasco of the Dominican Republican, and he won both his world titles as a pro (at bantamweight and then super-flyweight) on disputed technical decisions in Korea after he picked up cuts, although he did cement his reign as WBC super-flyweight champion with nine successful defences. Moon would certainly thrill hard-bitten Los Angeles fans with his willingness to wade in and dish it out, much as he did in Reno in 1986 where he won bantamweight gold in the world amateur championships. His three-round destruction of Shannon was also hugely impressive. Back in the 1970s, Japan's Shig Fukuyama made a name for himself in Los Angeles rings with a series of brave, fearless displays. Moon, whose victims include Gilberto Roman, Nana Yaw Konadu and Hilario Zapata, does the same.
