This. :deal Calzaghe is not a mover, it´s not his style he comes at you with his fast hands but he lacks defence. Nobody coming to Tiger survives this without having a very very good defence. Calzaghe doesn´t have one that´s good enough.
Calzaghe has too much speed, angles and movement for Tiger and has big reach/height advantage. He also has a quality chin for when he does get tagged. To beat Calzaghe at this weight you need to be good at range and Tiger isnt. A good right hand is important because its the punch hes most open to and Tiger just doesnt have the lead right to do the job. I'm sure when Calzaghe throws combinations, Tiger will drive him back ad make it hard for Joe but from range Joe can score first all day and yes he'll hurt Tiger too, in is prime he is a bigger puncher, he isnt a massive puncher but he can still hurt you. Calzaghe Clear or even Wide UD
