Hello Matt and great question again sir! Before I give you my list, I want to say that the late great Harry Greb would most certainly be on this list as everything I ever read about the man is incredible with the way he could throw punches nonstop and defeat men much bigger than himself because of great speed and tenacity but because there is no film footage I will leave him off this particular list but with knowing that he would probably deserve to be on here somewhere. It's been said that he was faster than ;lightweight Benny Leonard was by his contemporaries such as Jack Dempsey. He must have really been something to see.
