Golovkin would knock Froch, Bika, Kessler, Abraham all out. No contest................. Ward will find that Kovalev is a much better fighter than all those also, would kill them............
I will go with "entire Ward resume except maybe Kessler and Bika." GGG is a destroyer, but Kessler and Bika seem very durable. They might last the fight.
IMO probably stops everyone except Kessler. Bika would be like Murray fight. Froch would get out boxed and he would loose most of the exchanges if he tryes to make it a brawl. His footwork doesn´t allow him to compete at the same level. And Froch has been down or hurt by lesser hitters like Taylor and Dirrell.
