Jackarame,
I am all for giving the top talent the stage at a higher age group and Liam Cullen is one who played a number of U23 games when he was aged 16, 3 years ago.
But I think you have to be careful that the core of any age group is not disturbed continually, unless of course there are circumstances which prevent any age group from fielding their best eleven.
Youngsters are being given their opportunity in the 23’s more than ever this season and one wonders how the side would be affected further if the likes of Reid, Lewis, Blair, Maric, Zabret and Biabi had gone out on loan as this season is their 4th season at this level.
