Joe Frazier, the heavyweight boxing champion who gave Muhammad Ali his first loss, died Monday night at age 67. A representative said he had liver cancer. Between 1968 and 1973, Frazier won 32 fights – 27 of them by knockouts. In March 1971, Frazier became the undisputed heavyweight champion when he beat Ali in a 15 round decision in what was known as the Fight of the Century. John Hockenberry remembers the champ’s life and career.
