Rocky Marciano KO 13 Jersey Joe Walcott 1952

I dont see any wear-age on Walcott in fact he looks more fit than guys like Stiverne and many other heavyweights of today or the 80's I dont think age was the factor in that fight I think it was the S-Q-bomb and the understated ability that Marciano had to get incredible leverage and power on those 6-inch punches and fight in his short arm range by imposing his will and taking chances at getting hit. but that is just my humble opinion
