Not sure about 13's or 16s but both u14 and 15 GT out played NC considerable. Unless they have boarders missing they may have been a little under strength?
I think both schools were missing players due to rep duties (not u15) injuries (Gt from a rugby tournament during the week and NC from QJRU champs previous weekend) and holidays. So apart from also being a trial the games could only be seen as a guide rather than definitive.
I only saw the younger age groups before heading to Lang Park.
In the 15's despite GT losing majority of forwards from last year to older age group, due to new age rules, dominated up front giving the backs so much front foot ball that they found holes in the NC defense most of the day. A more experienced halves combination sealed the result for GT but it was hard for NC backs to do much when a lot of ball coming out was scrappy and under pressure. Not sure of final score but GT were up around 4 tries to 1.
In the 14's NC were down 8 players thru rep and injuries. GT were also down a couple as well. NC's depth in this age group is very good as it was a great contest. NC got off to a flyer with their winger capitalising on mistakes and cutting through some flimsy defense. However, to credit of GT they changed structure and hit back with No8 strong runs and offloads leading to some good tries and their winger then shutting down a lot of NC attacks. At end it was either GT up by a try or a draw.
In the 13's of little I saw, NC dominated up front but GT hung on by fingernails and got back into the match and I think forced a draw at the end. Both sides also lost some of their best players to rep duties.
