mike tyson is fun to watch, but in bodybuilding terms you can call him all drugs, without drugs most likely he could never be a prime boxer, heavyweight class is out of the question, he is a small guy in reality. the modern boxing stance, the importance on punching power, the lack of defensive skills, these are all things brought about by the inclusion of drugs in boxing. it used to be a sport about not getting hit rather than hitting as hard as you can
