So... don't pay so much for an unknown commodity!
i think both of you are very clever and make good points but the example of fresh 18 year olds is undenyable
if you want to be able to train up a "great" u21 team standard player you will probably buy him in his first week and people pay a million + for those 5k + MVP + players
then in their first game they foul out in 36 minutes, next game they foul out in 22 minutes, third game they foul out in 16 minutes
i know someone this happened to
they are screwed, you can't train a guy like that, you have to play rookies in cup/scrim matches or lose games, even when the player is trained he will still be a dud, you can never rely on him and he will also spend a week or two injured each season
so the only option is to sell him, but it has been 3 weeks of no pops bad minutes, now bad game shape and a record that anyone with a brain can see, so if you get half what you paid for him you are lucky
now you wasted 1/3 of your training for 3 weeks, maybe lost a game or two, and all the other good trainees are long gone
yeah the current system is great...
