See where your logic unfortunately falls down is that the closest thing to missing out on a decent player from our academy through lack of game time is Steven Lawless, hardly a superstar.
Here's a novel thought; if there's a player in the youth setup good enough for the 1st team he'll get a game sooner or later. There may be an issue in that our recruitment at youth level hasn't been good enough and we therefore haven't seen perhaps the influx of youngsters to the 1st team that you want. Even that I'd challenge though as we've got Cadden as a 1st team regular. Gordon, Maclean and Campbell in and around the 1st team and will clearly be given opportunities this season.
Even Kipre, whilst not coming through our system, is a 20 year old with potential clearly being considered for the 1st team.
