Three rounds. Golovkin destroys him with a body punch. Similar to the Macklin fight. Murray hides all the time with his double defense. It might even stop earlier.
5 rounds. When Sturm opened up on Murray he had him in serious trouble. Golovkin knocks people out who never even had been down.
Murray is a little too open when he lets his hands go. I think he will go the Geale route if he tries to stand his ground early.
that british glass will not hold up beyond the 6th. However, for fine british glass that is quite commendable.
Murray fights in a shell. This could actually go the distance. I find Sergio to be slicker than GGG and he had major problems breaking through
