As things stand right now, and provided we don't have any more injuries, this is how I would like to see our 1-7 when Walker returns.
Elliot (Turbo)
Garrick
Parker
Walker
Suli
Cust
Cherry-Evans
Move Garrick to the left outside of Parker, move Suli one out to the wing with Walker at right centre. Keep Cust at 5/8 with Daly and sorry, but drop Jorge.
Parker has proven he's a centre, not a winger and having Garrick outside of him gives him someone of pace he can send down the sideline, something he can't do with Jorge who is the slowest full time winger in the comp (remember when Sam Tagataese ran him down from behind? And Sam was not a fast front rower by any stretch).
The only question is how good is Suli under a bomb?
