Vince will start out at five eighth to keep it tight, he's an outstanding defender with an exlempary work-rate, I'm fairly sure I'm right to say he averages by far and away most tackles per game for an NRL centre. Thats part and parcel the reason I believe he'd be an outstanding back-rower actually, but I digress.
After 20 minutes, Ando will bring Motu into the frey I would imagine, pushing Vince into the backrow.
Brent Webb will work with Leuluai in the first 20 minutes in the kicking department, Louis Anderson has a fairly good kicking game too.
Rauhihi's loss is a big one, although I'm certainly not concerned about the pack, I think the front row rotation of the Cayless', Asotasi and Wiki is a particularly strong one. I know Kidwell had a terrific last test match, but I would have liked to have seen Paleaaesina have a burst if Rauhihi was out, from the bench, just to break some tackles for 2 x 15 minute periods.
