If Chad has the chance to beat Joe,he'll have to figt really smart and use different tactics through each round if he stands any chance of beating Joe.We all know Calzaghe has'nt got the K.O punch anymore,but by god he has speed,a never ending engine,tonnes of desire,a great great chin and a brilliant boxing brain to match!!It would be great if this fight could get made.Calzaghe would be my bet,apart from the lack of K.O punch power the guy has the full package to be unstoppable!!
