I agree, Frazier was fearless. Tyson was awesome beating people up but if they stood up to him he was lost. To my mind a great in boxing is not scared to go back into the ring against someone who had beaten them, Tyson managed this once and ended up biting Holyfield's ear and getting disqualified. In the thriller in Manilla Angelo Dundee pushed Ali out for the later rounds, Eddie Futch refused to do this with Frazier. Had the two cornermen been switched I think there would have been a different result.
I beat you to it by three minutes - scarily similar posts.
