I've watched a bit of him in the Super League, and I know its not NRL, but he is a 100% half back. Wigan have been using him at fullback recently to cover injuries and its no coincidence that they are going through a rough patch. The main thing he seems to have which we need is talk and direction, he is always near the ball and always talking and pointing. He single headedly dragged Salford, a perennial bottom team in the Super League, to the Grand Final a couple of years ago.
My hope is that his form in the Super League transfers to the NRL, that he can run the team assertively and Brooks can become a running 5/8 giving us a left/right foot kicking combo. Maybe Douehi becomes a Lock in the Radley type mold.
