thanks for the question mpoc,
1. The only thing we can really do is to make sure we are training the fewer players we do get well, although looking at the draft forum it seems like not many people got any! ;)
2. this leads on from the first question in a way. I would never want anyone to feel forced ot train a poor player with good potential to the detrement of their own team. Personally i know myself I wouldnt train a player with main skills of inept or below. On the other hand however it would probably be an option to use these players as a 5th trainee using 2 position training. So in an answer to this question then i would only advise this if it wasn't a detrement to the persons team.
3. I have nothing against training 19 yr olds, of course everyone would prefer an 18 year old, but it doesnt allways work out that way. i definitely wouldnt not train a player just because they were 19 instead of 18.
