CTPE...a simple reply is not as easy as it would appear at first glance. 16's tends to take in lads in both years 10 & 11, and some of the year 11 lads may well seek to play in the Opens with their mates ( provided of course that they are good enough - and the various school hierarchies concur !)
I am somewhat more cognisant of the GPS teams in this age group, and from last year's teams / results offer the following observations:
Newington had a very strong team, and went through undefeated until the last match against Riverview, where they got well & truly dusted in what I believe to have been a very physical game. 'View probably should have won more than they did, and may be affected more than others with their (current) year 11 contingent potentially opting for Opens in 2011;the lads from Hunters Hill could never be left out, and had a good group last year, but again with quite a number of year 11's this year, they may be tasked with bolstering the Opens too; Kings were always competitive, and should benefit with some NSW U15's heading out to Parramatta ( I believe), unfortunately I can't offer too many insights into Grammar & Shore, and Scots is always hampered in the 15's with the split year of boys heading to Nowra for 2 terms, which makes any assessment of their chances problematic. It could actually prove to be a really competitive and evenly matched age group in the 16's for the most part in 2011.
As far as the CAS & ISA teams go, if the previous post about a number of the NSW 15's forwards ending up at Trinity is correct, then they will definitely have an awesome forward pack. I would shudder at the thought of the respective families food bills seeing the size of some of them. I understand St Pats has a very good team in this age group as well, and you could never discount the lads from up Wahroonga way. Knox had a good team last year I'm told, and should be tough to beat again in 2011. I don't know much about the ISA teams in this age group, however, from a club perspective, I understand that St Augustines apparently has an exceptionally good team in this age group - which would correspond with the success that these players have enjoyed at Club level.
Happy for further input.....my eyesight isn't what it used to be !
But all in all, seems to be a pretty good age group across the board.
