do you have word on Hynes at all? He hasn't played a trial (nor as Ant Fainga'a, but I've read reports he will be fine). Have heard nothing about Hynes.
If Hynes is out, the candidates for the FB role are Morahan, Davies, Lucas, Toua and I will even throw in Harris.
First of all if we were to play Lucas as FB it means that Ian Prior becomes the backup 9 and this is a risky situation in my eyes. Unless we look to keep Lucas at 15 unless Genia goes down, and then still use Lucas as the backup 9. This is not an ideal situation. Lucas should be back up 9.
Morahan and Davies are both wingers. Even though Davies played 15 at school the bloke can't kick and his position play is not fantastic, add to the fact that his defense is woeful and you don't really have much of a fullback. Morahan can play fullback, but I prefer him on the wing. However he showed last year at the U20s that he is up to the role.
My preferred option would be to throw Aidan in the deep end and hope for the best. The bloke is a genuine FB who can play wing if need be. He has had a full pre-season, destroyed the brisbane club comp last year and if he can get confidence at this level could be one of the most dangerous attacking players in the land. Add to the fact that he has silky hands and an intelligent if not massive boot.
My wildcard for the fullback spot is Mike Harris. Now to be fair, I have not even seen much of the bloke play, but I understand he is a solid distributer and has an excellent kicking game. He is also a pretty big bloke and has by all accounts been training the house down. Im not sure if he can play 15 but he is worth some consideration at least.
