Unless you have a 5 or 6 season promotion plan then it is more cost effective to buy 27-28 year old players. I am sure the amount of competitive and active owners with promotion plans that take this long to develop is a relatively small percentage. The net loss that a team would take by buying a 27 year old and then selling him 2-3 seasons down the line is much smaller than the loss a team would take buying 23 year old players and then dealing them when they are 30. I do agree that trainees are necessary, and they too have a substantial economic impact. However, I do not find it suitable to build a team at the IV level around a young team. The talent costs to much, and you can't effectively train all of them. I also agree that 27-31 year old players do not sell for as much, but in comparison, they do not cost as much either.
