This is of course hypothetical because this fight could never happen!

But lets just say Calzaghe was fighting at Light-Middle weight i dont think PBF would be to keen to jump up to fight him like he did with Oscar.. Calzaghe's none stop work rate, and huge stamina and solid chin would simple overwhelm PBF, punches would be comming from all angles..

Im just trying to say is this the type of figher would could de-code PBF's syle and defence? Calzaghe does have a very individual style though.
