TRAIN SMARTER DOESN'T MEAN STOP TRAINING THEIR PLAYERS!
No it means, also train secondarys, or when the salary is starting to get out of hand, switch training spot/trainee or train stamina/FT/GS.
The fact that I find quite strange is that a team can't afford ONE of these players
As I already said, divI teams can afford them. Smart managers just are not willing to trade off strenght in every other spot to use them. Can you blame them?
You obviously can't stop NT player trainers, but one thing they should understand is: they should not be training those players thinking about later profit to their team, it's a one way street and all downhill at a certain point. Also any manager who wants to compete in a salary cap manager game, should stop fantasizing about those pushed to maximum NT "freaks".
