This is a come-backing , after his shooting Big Cat his muscle definition is markedly different. An interesting tit bit is that Tod Herring was one of two boxers who gave Williams blood transfusions when he was hospitalized with a357 magnum slug in his stomach. https://www.youtube.com/watch?v=PXNxTq9K2EM Don Dunphy the dean of boxing broadcasters refers to Williams as "once the hardest hitter in boxing"
I've just watched prime Williams versus 21lb lighter Billy the Barber Daniels on YouTube. Only the first 5rounds were available but to be honest I don't think Williams looked any worse against Herring. Perhaps Williams was slightly more wary of a man his own size against Tod but he was hurt bad in both fights. The rounds available against Daniels the fight looks pretty even.
I haven't watched the Daniels fight for years so I cant comment. I'm not really making any point here, just putting something up for interest.
