Ali-His talents were otherworldy
Hopkins-walks out of Graterford prison at 21,ends up holding the Middleweight title for 20 defenses. I watch anyone win 2 rounds,1 handed in a championship fight because of a sepreated shoulder,when they could have quit and gone to the cards,where they were well ahead on.
You have to admire that kind of heart
Mancinci-All heart,no art

Honorable mentions
Foreman-they said that comeback was a joke,right up until they had to put the title around his waist
Frazier-Guts and determination personified
Manfreddy-Every time he got in to the ring,you knew he was coming for you,even if he didnt win,he was ready for war
Billy Miske-the guy was a dying and took a fight to give his family one last christmas
Jack Johnson-overcame vicious racism,and was probably the sports first real boxer,not a Queens Rules boxer
