Also an advantage Tyson had is because of his speed of both foot(which hardly any realizes) and of hand is that once he did get inside he could launch a combination in the same amount of time Frazier would realize two punches... Tyson followed fighters alot quicker than Frazier as to tire them out quicker, and he had alot faster reflexes... You don't have to ask me who hits harder of the two even Frazier with 8oz gloves is nothing compared to Tyson who's power in real life is apparently something of a wonder
