RWC injury free gold pass,,,

if u had the ability/power to grant one player in ur nations RWC squad a gold pass which would seem them play the entire RWC tournament injury free, which player would u choose???

for me, it would be aaron smith.

my decision is based not on the quality of player (even though i consider aaron smith to be the best halfback in the world by miles), but on the level of depth the All Blacks would have to cover it.

IMO the All Blacks have the ability to cover nearly all positions with players who are as good as the incumbents.
halfback is the only exception. while tj is an excellent replacement for the All Blacks incumbent aaron smith should something happen to the latter, i feel like the All Blacks would notice the absence of aaron smiths more then any other player.
