One need only review their records to see who was ready to die and who was carefully guided and used - at times - smoke and mirrors to further his cause.
Well put,plus the simple depth of the division in their respective eras.Considering the level of comp that Saad had or his heart,could you imagine his responding like Michelczewski did in the first Rocchigiani fight?
I know that you are comparing their hearts in the ring but personally from what i know about both in terms of their character outside the ring i think it's insulting towards Saad to compare Holyfield and him. In regards to their in ring personas was Saad also a notorious headbutter who had steroid suspicions surrounding him? I understand where your comparison comes from and i'm not going at you personally, i just don't think much of Holyfield and can't stand him.
in terms of heart i think micky ward compares to muhammad, as does ali and frazier (from the thrilla in manilla, he would have died in that ring...literally)
