To answer your question, no. It would not draw fans in America. But who cares? They'd fight in Wales or Denmark anyway--and it would draw huge fans in either of those places. It would not be a PPV fight here (the US) though--it would be a free HBO WCB fight. Calzaghe-Taylor would probably get sold as a PPV in the states, but it would not sell well at all given how horrifically bad Taylor has been to watch recently (and the fact that Calzaghe is just not a big name here).
