and old foreman became a lineal champ again 20 years after he first held the championship. the ali analogy is misleading. true ali wasnt getting any younger when he fought foreman, but he was far from being shot. moore, walcott, charles and louis were all shot when they faced rocky. and also, joe frazier may be a little short compared to foreman but he was a natural heavy with a very scary left hook (the same left hook that brought younger ali down on the canvass). charles and moore fought their prime at LHW
They were all old former LHWs with several losses already when they fought Marciano and none of them measure close to a prime undefeated Joe Frazier. Add to the fact that Marciano struggled with them whereas Foreman blased Frazier 2X with absolute ease.
What's misleading is that you stating that older, yet formidable guys like Walcott, Charles, and Moore were shot. Like Ali these guys were still very formidable men when Marciano faced them. Charles busted up and nearly beat a prime Marciano so I doubt he was anywhere near "shot" as you say.... Walcott was the current reigning champion when Marciano faced him the 1st time, hardly a sign that he was some withered old man when he was the considered the best fighter in the division at the time... and Moore even went on to drop down in weight and succesfully defended his lightheavyweight title, again not the signs of an old shot fighter. Those guys, like Ali, were all-time great fighters who themselves were past their best, but defintely not shot at the time they faced Marciano.
those guys couldnt even sustain whatever heat theyd brought on rocky in the opener, thats not shot? they were past their primes when they fought rock. unless your definition of prime is a 38-42 y/o guy who has been into lots of wars. that moore could still fight and beat somebody at lighter weights only means hes great at that weight. doesnt mean anything at heavy.
Moore beat the number 1 rank contender to get rank vs Valez. Moore clean his way to a shot vs Marciano. Hardly signs of a shot fighter. That and Moore was able to stay in the top ten heavyweight contenders when he retire, means in 55, He was a pretty good fighter. May have been Heavyweight champ if Marciano, Patterson or Liston were not around.
Marciano: The fact that he never lost and most "experts" say "well he wasn't really a HW so I don'r rate him" But he sure as hell beat a lot of great HW's!
Marciano should rate higher, but they are both in the same clutch between 9 and 15 for me. But a higher rating for either is easy to justify dependant pon your criteria.
A fighter can only be rated based on his fights during his time and Marciano fought anyone who was available to him. He never ducked anyone or lost to anyone and that in itself is a major accomplishment if we look back at all of the other great fighters in all of the other divisions. Somewhere along the line everyone else has lost on a given night, but not Marciano! What was so terrible about his opposition? Joe Louis may have been past his best, but he was on an 8-10 fight win streak going into his fight with Marciano and his wins were against decent to good opposition. And besides Walcott, Charles and Moore, there was LaStarza, Matthews, Layne, and many other tough fighters with very good records.
