Jerry Quarry, Joe Frazier and old Big George.
Loved Quarry, a brave too small heavyweight that Big George called the best fighter who never won a belt. Would be a crusierweight champ now. Joe Frazier who was a born warrior who never took a backward step. Threw the left hook with massive power and wore everyone else out ,,,,,except big George Foreman ( Just two big and strong) and of course Ali, Ward and Gatti as exciting as they were in their 3 fights never fought on this level. And who could forget Old Earnie Shavers who could down buildings with his right. Ah , the golden era of Heavyweights
