Doc, New South Wales boys are all 18 when they finish school, so why does QLD rugby struggle and NSW doesn't when they are "suffering" the same problem.
It's also unfair to single out BSHS as "the big reason why QLD rugby has struggled" in the past years, when nearly all schools allow their pupils to do senior over 3 years if they have heavy sporting commitments. A players development is also often enhanced with an extra year at schoolboy level, considering Feauai was initially asked to repeat Grade 12 by the Reds, and would have except Reds pulled the plug on it in the 11th hour.
And regarding your dig at state highs "young talent", of their 9 Australian Schoolboys last year;
2 were 15 (at the time)
2 were 17; and
5 were 18.
Only 3 did senior over two years.
With due respect, you're prejudice towards State High should be vented elsewhere.
