Not a chance in hell...He'll replace Nonu for the World Cup for sure..
barring injury, or a massive drop in form next year, SBW will NOT start a major Test match ahead of Nonu... There is no chance the AB coaches will split up probably the no1 centre combination in world Rugby in a world cup year... that would be beyond stupid...
SBW, if he keeps up his development, will be the impact player in the last 20 of a Test match.
