Ewps, I thought this was heavyweights. Not sure where to put this, so forgive me for beng such a noob. 1) Muhammad Ali (Unbeatable in the 60s, was only beaten by great fighters in the early to mid 70s. No one could touch Ali in his first run as champion, and I personally believe he would have beaten every other on this list during that time.). 2) Joe Louis (do I really need to explain?) 3) Larry Holmes (Greatest heavyweight jab ever, and nearly as great a ring general as Ali...despite the cries of lack of competition he was unbeatable post-Norton to 1985) 4) George Foreman (just take in his entire career. Wasn't much of a boxer, but such a devastatingly heavy puncher with the added gift of being a truly terrifying finisher. Unbelievably enduring, resilient in the 90s. He had an outrageously great and heavy (but woefully underused) left jab. ..had he employed it a long with more head and foot movement he might have overtaken Holmes on this list) 5) Jack Johnson (An all arounder, like Louis. Possibly the most tragic casualty in boxing due to the politics of the time) 6) Jack Dempsey (Even moreso than Tyson and Frazier, the most id-fueled swarmer in heavyweight history. Very much like an unstoppable force of nature at his best, regardless of being so light for a heavyweight) 7) Joe Frazier (Greatest left hook and, when he beat Ali, probably better than Foreman and Dempsey ever were. He's ranked down because, like Tyson, he really didn't last that long at his peak.) 8) Rocky Marciano (I'm a bit grudging putting him over Liston and Holyfield due to the rawther, uh...elderly nature of his competition. Hard to fight that record, though) 9) Sonny Liston (faster than Foreman and heavier-fisted than Tyson and Frazier. Again, his peak just didn't last that long imo) 10) Evander Holyfield (fantastic heart, terrific and unorthodox style...at his peak Evander was a terrific sight to see imo. Had the health issues not existed he would have more resoundingly beat Holmes and Foreman...and probably never lost to Lewis and Moorer).
