Yeah, I mean it's hardly an insult to say that Marciano would have beaten anyone who ever lived, who weighed less than 200 pounds. It's actually a very big compliment.

It's just that between the advent of prenatal drugs, better dietary knowledge and the possibility of steroids, the heavyweights jumped 50 pounds in weight and 3 or 4 inches in height in a single generation. And in all fairness, the heavyweights of today are even bigger than that!
