"Had Marciano grown up in this era, eating the beef we eat today which is loaded with bovine growth hormone, and with this era's easy access to supplements and yes, even steroids, then a contemporary Marciano would have weighed 25 or 30 pounds more. And you're right, I still don't know if such a bigger Marciano could take Foreman--maybe, maybe not."
Someone with Marciano's reach and frame would be foolish to add enough to mass to fight as a HW instead of a cruiserweight in today's boxing world. As a cruiser or LHW, it wouldn't surprise me if a prime Marciano could remain undefeated in this day and age.
"But what I do know is this: Despite being a white guy, Marciano was less susceptible to cuts than Vitali."
Vitali Klitscko had exactly one fight stopped by a fluke of a bad cut. It can happen to anyone. Marciano took cuts that probably would have led to a TKO if he fought today. Many fighters of that era did. The rules are simply enforced differently today. Does it hurt the careers of some fighters who are otherwise excellent? Sure, but theres nothing to be done for it.
"And this much is for SURE: Marciano was much less susceptible to shoulder and knee injuries. He had staying power, unlike this Vitali guy who came and went and now he's gone."
Marciano was much younger the time he was fighting, much smaller, and really, his pro career didn't last much longer than Klitscko's. Not to knock Marciano, it was smart for him to retire when he did, just as it was smart for Klitscko. 37 is not too young to retire, as Marciano demonstrated against Louis...care to call the Brown Bomber a quitter, or argue that the loss against Rocky tarnished his record?
Klitscko's record can't be argued away. He knocked out a 91% of his opponents, often in the later rounds, one can't argue with that. I don't care who he was fighting, especially with today's big HWs, that means raw power. He was never knocked down-once again, especially with today's big HWs, that means an incredible chin. Marciano, tough as he was, got knocked down twice by much smaller beasts than the ones Klitscko faced. He was never behind on the score cards-he was a far better boxer than the other big men of boxing lore like Foreman. Those who view the past with rose-tinted glasses and those who believe the black is invincibly superior as a boxer, and those who have seen Rocky IV one too many times may with to discredit Klitschko, but the arguments just don't work.
Lots of boxers get cut, lots of boxers tear their rotator cuffs. The Gods of odds decreed that it happened to Vitali at the worst possible time.
Oh, and I'm very sorry to fans of classic boxing who don't think the modern HWs are as exciting as the fast cruiser-weight size fighters of old. But HWs have been getting bigger throughout the entire 20th century, all in all, bigger men win fights, a little late to start complaining about the RUSSIAN giants when we Americans have been training Black skyscrapers as fighters for 50 years.
