Golovkin is a modern day prime Kostya Tzsyu, he would present Mayweather with a fight he could genuinely lose, but only due to his accuracy as a puncher with both hands and one punch knock out power, more than likely mayweather would out point him over 12 rounds in a fight where he would be on his bike all night keeping his distance. Froch please shame Calzaghie isn't still fighting he cannot fight a good boxer, Ward showed that the first time, no point them fighting again, they are that far apart.Calzaghie Ward would be a great fight as both guys have good speed and movment both are well above the likes of Froch in terms of skill, taking nothing away from him as a genuine champion but hes limited when talking p4p
