I buy youths pretty regularly, and my advice is much the same as above... Train them, play them, and examine successful players of the same position ans see how their Skill Points are assigned, and work toward assigning them similarly on your youth. The problem with youngsters is their very even, and often need to be tweaked to get the best performance out of them. I ignore ratings until I have got their skills where I like.. if they then don't work... sell.
