Surely the 16 year olds making the biggest impact at that level are Cameron and Moretti. Both playing in teams that are doing much better than Barker.
Cameron is playing in an undefeated first XV and Moretti is playing in a team that will come in second to that undefeated team.
The other players selected in the back row are Trobec, who could play in that Knox undefeated team easily. And Murphy, who could do the same at Waverley.
The only reserve back rower appears to be Ginis, but he can also play second row, front row and centre. They have selected a team that can play tournament rugby and it shows in the selections.
Reimer played one quarter yesterday made little impact and has been playing in a team that has been doing very poorly. That is why he is not there.
If he was to be picked in the opens back row instead of Margin, Basson, Kemmeny, Clifton, Stead,Tuitavake, Hzardaker, Osullivan, Moretti. Who are all the form back rowers in the open Comp and who are all in teams that are playing better than Barker, I would be very surprised.
