I'd expect Paddy to get the wing spot due to being an out and out winger and Craven to drop to the bench due to his versatility. Craven's a top player in the making and is probably a stand off but he is still learning his trade.
I'd expect our backs to line up like this;
Briscoe
Ah Van
Isa
Phelps
Flynn
With Marsh in the mix and Phelps & Cravens versatility there are some interesting choices for Betts.
