bad hands have limited a lot of fighters. I remember Greg Haugen being pretty impressive and then he just stopped knocking out guys, Ali was said to have serious hand problems from 71-74 when he came back. He actually had his hands shot up with Novocain. They say Jake Lamotta had hand problems and that contributed to his piddly kayo record but he was also known to have tiny hands, (yes, i know, some people think that has nothing to do with power). The hand are a complex part of the body and not meant to be banged on any hard object, just feeling how small the bones are makes you realize why fighters have issues.
