This would have been an exciting fight.

GGG is actually a small middleweight, whereas Froch was a seriously big supermiddle. Froch had that iron chin and the will to go to war. It's feasible he could have bullied and overwhelmed Golovkin, using his size and strength to hand out a messy battering.

I doubt it though.

Golovkin, in his prime, was a fearsome proposition. A genuinely elite fighter. He certainly had freakish power, and I think he hits harder than Groves. He had world class boxing skills too which is often forgotten.

I think he uses his technique and strange punching angles to hurt Froch early. Once Froch is that little bit more wary, GGG uses his superior boxing skills to pile up the points and dominate a cagey boxing match where both guys are respectful of the other's strengths.
