I think Harry and others who have missed out like Brandon P-A (whom I also rate) have to be a little circumspect.
As Brainstrust said on another thread:
If you have heard Eric Rush the former All Black speak he tells a great story about when he was growing up. He always trialled but never got picked. His father would always say "Don't worry because its just one blokes opinion, maybe the next guy will think differently". When he excitedly phoned his father to tell him he had been selected for the All Blacks, his father congratulated him, but reminded him "it's just one blokes opinion. Don't get a big head, because the next bloke may not like you."
Let us play with some numbers and history.
Australian Schoolboys started in 1969.
The first to make Wallabies was Russell Fairfax in 1971.
Fairfax was Wallaby #546. Jesse Mogg is the Wob # 869 (according to wiki), but Chris F-Sautia has debuted since then so he is #870.
Since 1971 there have been 324 Wallabies selected.
Chris F-Sautia and Liam Gill were Schoolboys in 2009. The 2010 onwards schoolboys reps are too young to be counted in this analysis.
Between 1969 and 2009 (inclusive), there have been 1066 boys represent Australia A or Australia Schoolboys.
Of these 1066, only 157 have gone on to be a Wallaby (14%).
Conversely of the 324 new Wallabies since 1969, 167 did NOT make Australia Schoolboys, or Australia A Schoolboys (51%).
So What:
1. Aust Schoolboy/Schoolboy A selection is a very poor indicator that the lad will become a Wallaby.
2. In recent times, more Wallabies have been selected who were NOT Aust Schoolboy/SchoolboyA representatives than those who were.
Cream rises to the surface, and there is every reason to believe that Jones and others will do well in the future provided they keep applying themselves, and maintain their fitness.
John Eales first rep team was the Aust Under 21's (IIRC).
I would commend anyone connected with Jones and Paenga-Amosa (and all others who have "missed out") to pass this information on to them. Hang in there. The sun will still come up tomorrow.
To those selected: Jolly good job and enjoy your time in the sun. The tour will be memorable, and it doesn't get any better than this. There is every chance that you will be one of those schoolboys that DOES become a Wallaby, if you stay fit and apply yourself.
Don't forget to study for your Matriculation exams in the mean time. Doing well in those must be your immediate goal.
