Why don't more fans appreciate Joe Calzaghes fighting style

Of course Joe landed more shots throughout his career.

His biggest strength was his engine and the volume of shots that he threw.

Roy didn't need to throw as many shots as Joe.

Regarding defence, Joe was always relatively easy to hit, especially with right hands. It was a big weakness of his. Whereas Roy was very awkward to hit clean.

Roy was just simply a better fighter in his prime.
