They have publicly stated the gamble they took naming the 31, or rather, dropping the 10. I think the gambles (in order of riskiness)
1 leave sopoaga and rely on carter
2 leave dagg and rely on barrett
3 leave piutau and rely on nms
4 leave jane (less injured) and take naholo (more injured)
Don't think there are any gambles on the forwards
There is no way Sopoaga would of been taken in place of Carter, and rightly so.
Apparently not, according to Justin Marshall's chin wag with Grant Fox.
When and where was that written or shown?
