Wow! Good question! #1 Hearns very few fighters in history has KO'ed as many fighters considered "granite chinned " #1B Arguello, if their is a such a thing as a "perfect right cross " Arguello had it. #1C Duran, hooking or cross or uppercut, each effective, each he KO'ed a fighter with. #2 D. Lopez, great right hand power. #3 M.Saad Mohammed, most times he was at war, his right hand saved him many times. #4 W.Gomez, at his best fighting weight was lethal with any shot. #5 G.Foreman, he actually lifted a over 200lbs man off his feet with a right hand. #6 J.Jackson possibly the hardest punching fighter in history with any power punch. #7 J.Mugabi his right hand was not as smooth as most fighters above him. But effective. #8 E.Rasario a viscous right hand puncher, just ask the" Coconut Head". #9 M.Tyson right hook to the body, followed by a right uppercut, beautiful and viscous. # 10 R.Leonard, underrated power, usually overlooked because of his combo punching, But film don't lie, he KO'ed many with his cross .
