So by better nutrition and training facilities you mean healthy food and building muscle? I fail to understand how a more muscular Louis makes him 'school' Vitali. It would do no favours to Louis whatever, apart from slow him down. A prime Louis was amazingly strong and agile, his speed was his game, weight training would only make him slower. Anyway, even if he was brought up with the right supplements and food, do you think he would grow that much more? I doubt it my friend. Joe Louis is my all time favourite fighter, but I don't see him outworking Vitali. His arqward style, height and reach advantage and his granite chin would be too much. Now Longcount, take one for the team.. and **** off.
Improved nutrition can lead to a size increase in the population. Joe Louis likely would have been taller if he had access to better nutrition when he was still growing.
