There are always clamours to include youth players. For the last couple of years many of posters on here have suggested Thomas, watt and cadden are all worthy of inclusion in the first team based on their performances for the u20s. However, the difference in levels from u20s to first team is huge. Cadden granted has managed to bridge the gap but the other two will struggle in my honest opinion as will the others at this current moment in time. Indeed watt is struggling to get much game time for Stranraer in the third tier.
Craigan and McGhee are much better placed to judge on whether they are ready or not. I'm happy to trust their judgement.
