Probably as you are a blue square south team the game thinks that older, more experienced players, are less likely to play at such a low level, whereas younger players are more likely to move anywhere that they can get first team games.
I love little kids ... lol! ...not in the sick way ... Im Hull, have no money at all ... I have stocked as many 15-19 year olds with as many -9's and -10's as i can get, I have sold alot of the older blokes to get the money to get them and keep them ... its a catfight to stay up but im now 6 points above relegation in Feb of the first year!
The future is bright ... i need to battle for a few years to stay up then i should go kick arse when the youth train into wonderkids and champs!
