Personally, I think it's a culture and chance issue.
Notts is in a position where it's ambitious, and it might be seen as a luxury to play a youth prospect or young professional. I have been very critical of my disappointment regarding this over the years, as I have seen enough wasted talent. If Stuart Maynard could be bold enough to ensure that the likes of James Sanderson managed to start at least 12 games this season, even if the majority were low-key cup games, it's still vital minutes which lead to experience.
Experience which isn't always gained by going out on loan, this is more clubs hoping to excel the progression so the young player(s) are near to the first team in terms of footballing minutes.
Without really committing, we'll never know if any of the youngsters before their release if they will reach the ability where they can become a strong first team candidate.
Our academy is very good. I have seen training sessions before the issues under AH, and I am sure it's returned to that level, if not better under the Reedtz. The thing is, the majority of fans say they want to see youngsters given the chance but quickly turn against the idea. I have seen no end to promising players falling to criticism whilst they are learning. It's not productive, especially when it's over critical or directly put to them.
At the same time, due to the pressured environment managers are less likely to give youngsters the chance because it could be them that ends up being fired if results don't go their way.
Crewe Alexandra have a decent youth setup, as do a few other clubs, where players are given minutes and nurtured. Notts must start giving them better opportunities, and because it can work, the pay-off is highly beneficial. Especially when players start performing at a higher standard than what you are playing at.
