I'm going to be in a minority here and say he goes the distance. From what little I have seen of Murray he seems to have a tight guard and size on him. However with GGG's streak its not wise betting against the KO.
Under 6 rounds, I'd be very surprised if it went the distance. Murray isn't as good as what some people seem to think and they're basing it off his losses. against Martinez & Sturm.
He's tailor made for Golovkin, he has a come forward style and carries his guard high exposing his body. He can't beat Golovkin in a brawl nor can he out box him. Golovkin's hook to the body will be the telling punch.
The only thing he does have is his size but you all know the saying... the bigger they are, the harder they fall.
