Joe Frazier - 1970s Heavyweights

"Smokin Joe." Say those words and diehard boxing fans know exactly who you were talking about. One of the hardest hitting and grittiest fighters in history, Frazier and Ali staged three of the best fights in their division in the history of the sport. In their third fight won by Ali, the late and former Cassius Clay said he felt like he was going to die in the ring. Frazier would get smashed and humiliated by George Foreman but in 37 pro fights, Frazier lost just four times (Foreman, Ali twice and Foreman a second time). 27 of his 32 victories were by knockout and anyone who knows his story can never forget his classic 1971 fight with Ali when he knocked down Ali with a powerful left hand his bread and butter.
