I hate to use this cliche but styles make fights. Froch in his prime was a difficult out. Really unorthodox in his approach with a killer right hand and a world class chin to back it up. There is no shame in losing to one of the best fighters of our time. He's also most likely a pretty good sized light heavyweight at fight time. Golovkin has a world class chin also but he's faced nobody who punches like Froch. I just don't see Golovkin walking Carl down and having his way or sticking his chin out and asking for one with a smile on his face.
