Who was the most physically talented boxer

If that's your line of reasoning regarding Sanders then why not Tony Galento? He never trained seriously, was about 5'9'' and weighed 235 pounds and yet hurt Joe Louis badly in a fight. Just think what he would have done if he didn't eat all that food and drink so much beer during training. Sanders never showed any other outstanding physical abilities other than being able to put Klitschko on his butt, which doesn't prove that much in my eyes.

 

Sugar Ray Robinson??
