I understand what you mean it's kind of like Canelo/Golovkin 1, now technically that's also a fairly close fight in region of 7-5 for Golovkin. Yet most people consider that a robbery, because theres no way you can have Canelo winning 6 rounds in the fight. Just for the record Eubank also believes he lost the 2nd fight with Benn, but also believes he beat Collins in their 1st fight aswell. Eubank actually should've had 2 knockdowns scored vs Collins which isn't often talked about.
I'm with @My dinner with Conteh here, on Benn being robbed in a rematch as well. Golovkin was far superior fighter, in basically every department. Only advantage for Chris would probably be his footwork - but all it could do for him is allow him run from corner to corner for 12 rounds, enough to not take too consistant or sustained punishment and perhaps go the distance.
I've never really held the Collins defeats against Eubank too much to be honest, same with Benn. Fair play to Steve, he saw a great opportunity to get a slice of the "UK pie", after being beaten in previous goes at the title. But I always felt he was a bit 'right place, right time'.
