He may not have "ducked" anyone, but he also didn't make any efforts whatsoever to pursue the best opponents available for much of his career. I'm not a fan of Calzaghes and I love to watch Froch fight, however I do feel that Joe would probably have been able to take a decision over Froch at his best. However, his resume is already a joke compared to Carl's and he commands MUCH less respect for this imo.
