Hoping the same for Moylan both of them are way to small to be fullbacks, they are probably the 2 worst fbs in the comp bringing the ball back.
Tomkins should of been there this year, Warriors should of kept Locke at the back.
Fullbacks don't need to be big at all :/. Bowen, Slater, Stewart, milford, Tomkins, barba (before he went off the wall) etc. There are plenty of great little fullbacks. In general fullbacks aren't really that big and it's actually a disadvantage if it impacts your mobility. The likes of Hayne, Dugan and Inglis have changed things slightly but you don't have to go down that route.
I'm still of the opinion that guys like Inglis aren't optimal at fullback. He gets away with it because he is a freak athlete but he's still a liability against a player with a good kicking game. Basically outside of the odd exception small fullbacks are the way to go.
Not sure how 5/8 helps either. In the halves you're defending against centres and wide running second rowers, this is hardly the place to hide if you're small and a weak defender. If anything fullback covers that up more, you're more doing cover defense than tackling big guys head on regularly. You put someone like Moylan in the front line and teams will be running forwards at him all day long.
