I'm too young to actually remember watching Frazier fight; my father, however, was not. As a result, he was a Frazier fan, and I've inherited some of that fandom. My father admired him not just for his skill, but for his mannerisms: he saw Frazier as the consummate professional, the kind of fighter who did his talking in the ring, with his fists.
Frazier was one of the defining forces of boxing in the 20th century. His rivalry with Muhammad Ali was legendary, and with good reason. In any one of their fights, the faith, tenacity, will, and skill displayed by both fighters is absolutely incredible.
The world is a little poorer without him.
