The biggest difference between Calzaghe/Hopkins and Pavlik/Hopkins is that Pavlik requires to be set when throwing punches, while Calzaghe throws punches regardless.

Calzaghe threw punches even when not set or out of range. he did not let Hopkins movement or countering deter him, which in itself, made Hopkins a bit hesitant.

Pavlik would not throw punches when off kilter. He seemed lost last night. Weight or anything had nothing to do with him losing. It was Hopkins movement and timing that got to him. He was reacting to Hopkins instead of making his own fight. Joe fell into Hopkins trap also, but not nearly as bad as Pavlik did.

It is strange really. I am not sure what Pavlik was expecting going into the fight.
