How about Max Evans at Fullback? Bit of a risk, but it lets you get Lamont, Ansbro, Evans and Walker onto the pitch at once, and Southwell off it. Or just Evans at 12. I really don't think he's a winger. He has all the atributes, but neds to get the ball more. Hopefully he proves me right today and ruins everything that comes his way.
Why do teams keep shifting their most gifted footballers about to potions in which they won't get the ball? Hook at Fullback, Max Evans on the wing, Aled Brew at flanker (Not a gifted footballer as such, but one of the only examples I could think of. Not as good a point as I thought it was.) I expect NZ to pick Carter at tighthead in the run-up to the World Cup.
