Murray has shown why he is most people's first choice alongside Johnson. He has been magnificent around the park in Scotland's games, and of course, his lineout has been exemplary. Grewcock's surge in form has taken the edge off Murray's challenge, but his cleaning out of John Eales still makes him a prime candidate. Possession may be scarce, and being able to steal Aussie lineout ball could be vital. Anything to put Eales off his game, at least.
