Being able to afford a youth set up is all about faith, hoping to unearth an absolute gem. Thats the way small clubs plied their trade in the past, but now the big clubs scouting network is so proactive, you are liable to lose these gems to the likes of Man U, Chelsea, Arsenal etc etc before they even get near the first team. You hear of these clubs after players of 13, 14, 15 and 16 thinking they can improve their development with their higher regarded higher paid youth coaches, but it will starve the smaller clubs of that big pay day, as they only pay towards the small clubs time and effort in coaching the youngster. You may get £100k for a player worth £1-2m a couple of years later, although finding that gem might be one per generation.
Consider this, we have 11 non highlander under 20s in a squad of 16-17, but 4 or 5 go on to our first team, would we consider that better than all highlanders, 1 getting to first team but we get relegated. Terry and Mo will be doing what they think is best for the clubs future, as to bring our club down will ruin their career, they are here to do everything to succeed,
