We have academy players out on loan - presumably with a view to getting them first team ready.
Hastie looked like he'd be the next one to step up, although I haven't kept an eye on his recent progress.
Newall didn't come through the academy, but is only 19. And Semple is supposedly the next big thing, but just a bit too young for first team development.
Dom Thomas should have been ready this year, but we all know that story.
