Re: Wladimir Klitschko vs. Rocky Marciano
to be honest in today's era of pre fight weigh ins and weight cutting rocky would be 175lb or even 168lb. what you have to also take into account though is if Klitschko was born in Marciano's era and fed on his diet, would he be the size he is? undoubtably no, same goes for if Rocky grew up in this era, no doubt he would be 6'2 to 6'4.
It's like comparing messi to george best, no way was as fast, fit etc. as messi is but then again he didn't have all the nutritional advantages and messi doesn't have to deal with much bigger blokes who can get away with taking your legs out.
