So true mate.
A mildly similar experience I am having in non league. Last season I was asked to lead a new u17 and u18 setup. My only direction was to produce players four our u21s and first team. Club not remotely interested in titles etc, just getting local lads through. We had a div 2 level squad but I put them into div 1 to fasttrack development. By the end of season 5 17 year olds are playing u21 football, 2 of them vying for players player by all accounts. 1 17 year old played last 2 months with the first team. It is a good success rate.
This morning I ran an open session for next years 17 year olds from ths region. I had all the club there, u21 and first team coaches, chairman, kitman, the lot. 36 lads came, 20 I knew and had invited, 16 I didnt but had seen the advertising, or other lads brought them. The standard was superb. We are going with 2 u18 sides next season. 2 lads this morning are going straight into u21s in pre season. 1 18 year old turned up and he is in with first team for pre season.
I know it is levels away. But if you demonstrate you will play them, and keep playing, word gets around quickly and people want to be a part of it.
