I thought everyone knew Holyfield was dirtier. He head butted constantly. You can list the fights Tyson bent arms. Do you care to write all the fights Holyfield butted repeatedly? It wasn't just a case of his aggressive style either. The tougher he was in the more he did it, when things weren't going his way the more he did it. It was deliberate. Holyfield was a butter and no sane person will deny that.
