I personally think carl froch is the closest any fighter can get to beating calzaghe...obviously calzaghe you would say has the better stamina, work rate and overall is the better fighter... BUT lets face- calzaghe would probably not hurt froch whereas calzaghe has been gone down in hes last two fights to fighters who dont hit like froch. Also make no mistake froch can box...he looked realy good when he was throwing the jab out there and moving. At times he looked gassed out tho and slow- although whenever he wanted to get to hes opponent he got to him-like a cobra Just throwing the senario out there. Calzaghe is a great fighter and froch i think can become one
