Hopkins underestimated Calzaghe, Pavlik underestimated Hopkins

Nope, Calzaghe and Hopkins are a level above Pavlik

Nah. Hopkins gave Calzaghe credit in a roundabout way in his post fight interview. Styles make fights. Pavlik is just too one dimensional to deal with a fighter like Hopkins. Calzaghe made Hopkins work for all 12 rounds, made him use his legs and had him hanging on at the end. Pavlik fought at Hopkins' pace the whole fight, couldnt get his jab off and just walked straight forward into counters
