If he's out, I'd like to see them stay with the current squad, rather than drafting another Europe-based player in - sorry LFG.
6 Letoa, 7 Samu, 8 Valetini, 20 Swinton.
Otherwise, I think Arnold is the only drafted player who has performed at all ok. Still prefer to go back to Philip and Swain to start and Rodda on the bench (too many errors against England). Latu offered nothing more, in fact looked a step down, on FF (Folau Fainga'a) and McInerney.
In the back three, I'd look to move Kellaway again to 15 (hardly sighted on the wing) with Perese and Daugunu on the wings. Tom Wright has a few too many minuses against him; poor tackling technique, prone to brain explosions.
