When NZL and SAF can run out an U20 team for the U20 World Cup that has large numbers of Super Rugby and ITM/Curry Cup players, then we should be encouraging out top level U20 players to be playing their Club footy at the highest level possible (NRC or Premier Grade Rugby, not Colts).
Given Supply and Demand (approx 25-30 Aust Schoolboys/Barbarians (6 points) and 60 NSW I, NSW II, CS (4 points)), some clubs are always going to land a few more high point players than others. Looking back over the various "Which Clubs Are the Class of 201X Going to?" it would appear that each year 4 clubs take the lions share of the Rockstars with the balance (usually 1 or two each being fairly evenly distributed}. Of the Lions Share group, 2 clubs are regularly there, and the other two recipients drift in and out of favour with the recent graduates. For a while Manly and Norths seemed to do well, but of late it has been Easts and Gordon that have recruited well.
It is not always clubs actively recruiting players. Gen X/Y and their parents (and heaven forbid Player Managers) are quite astute at reading tea leaves and working out which clubs will give them the best advantage of advancing to the next level whether that is U20's, NRC, or Super Rugby, based on their perceptions of the relative strengths of the colts programmes, club networks and opportunities.
This year Eastern Suburbs have landed quite a good crop of talented new colts players with impressive Schoolboy rugby CVs, many of whom are former Beastie juniors that attended local high schools (with or without enrollment anomalies), although they have been out of the Beastie Junior Club scene since U14s. Good to see some loyalty, but without crunching the numbers, I think they may struggle to stay under the Points Cap.
