Given Sloan is at fullback, he will likely see more ball and show us a glimpse of why we thought he was going to be something however I can't see him putting any pressure on Gutho.
He has great speed which is sometimes enough to score a try but I don't think he has much else to his game.
Lawrie, great if he's lost weight, so he might play more minutes but what else does he bring, no offload, no quick play the ball, no footwork, no aggression.
Hopefully being lighter means faster line speed and more meters carrying the ball, improvement on the basics.
