Ah, memories. People tend to greatly enhance the "legend" and love the back in the day stories.
Joe was a top fighter but today alone I have read he is virtually unbeatable and was always exciting to watch ( hence why he was pulling in 2k at Cardiff ice rink when he was WBO champ )
He would have beaten Froch, yes. But without breaking sweat?

is this the same guy who I certainly see sweating against Bika? Calzaghe loved a tear up, he would have gone into the fight with little love lost for Carl. Are people telling me he would have not engaged and stood and traded at some point with Carl? Of course he would!
He would have decisioned him, pretty clearly but by no means would he have run rings around him.
Never seen anyone here claim Froch would beat him. I have seen many claim he has more balls and was more willing though, and that it showed in their respective records.
