Heard they had their 4 new to school plus a number of refugees, which is a loophole that one can use to bolster sides.
This is incorrect. They had 1 new to school player in their squad at nationals, a year 11 playing in midfield.
Not quite, there were a handful of boys that moved to NC this year. Its just that only one of them that moved were in the tournament squad. But there were at least two others that were playing First XI in 1st Div if I remember correctly, just weren't selected for Nationals. Its also not a major loophole, (as college found out) when one of their qualifying results (8-0 vs Marlborough) was overturned as they 'played more than two boys new to the school this year'.
