How does the Classic Forum rate Sergio Martinez ?

Kinda... After the fight with Junior (which was supposed to be Sergio´s last) the best known opponent Golovkin had beaten was a shot Kassim Ouma, that was not the best middleweight in the world, the bar was low but not that low, I don't remember watching Golovkin before the Proska fight, I retro watched sure, but I don't remember watching Golovkin vs Ouma.
