Then we may as well not turn up. I can't think of a player who is currently kicking better who is good enough to play as 10 for the Wallabies, i.e. who can do all the things required.
But I suspect someone will correct me soon enough.
Unless we're lucky enough to build a genius kicker that needs no technical and mental skills assistance to get to an 80+% level - and they are exceptionally rare - even very good kickers in pressure seasons need the regular support of a seasoned kicking coach, and the better the kicking coach, the better the consistency of results.
J Wilkinson for years related how he consistently retained M Alred to aid with his kicking and to assist in making very fine adjustments to his technique, stance, angle and generally mental focus disciplines and so on. (Alred is rated one of the best kicking coaches in the world btw.)
Partly I suspect as Cheika was heavily compromised in his free time doing dual coaching roles with the Tahs and Wallabies, he has failed to assemble a total coaching capability for the Wallabies that goes anywhere near that possessed by, just for example, England and the ABs.
What consequences flow from this, we will know come November if not before. What cannot be disputed though is how risky such a comparatively under-resourced national coaching group is, especially in a RWC year and where such is Cheika's first full year as national coach.
