So - just to clarify because I think it has been taken a bit out of context.
I never suggested train primaries endlessly - correct. I never suggested to never train secondaries.
My suggestion was merely an alternative to the majority secondaries training that others were suggesting for the coming season. These are some of the con's/pro's of my suggestion.
If he trains majority secondaries for 1 season - he ends up with a player that
a) he can't really use in league games because his primaries aren't good enough.
b) he ends up with a player that no one else will want to play in their league games.
So by training majority secondaries in the coming season, from a commercial perspective, he limits his selling audience at the end of season, to only people who want to train him. Bad thing? Maybe... a little bit. he could still sell him and make nice profit. But as a player, he is still useless.
If he decides to train majority primaries he ends up with:
a) a player that can play in his league games, thus making achieving further training minutes easier, plus the added financial benefit of not having to have another player and accompanying salary.
b) A player that if he sells, will still sell for a good profit.
c) If the owner promotes, he also has a chance of having the trainee's be useful players in that division.
d) A player that, if he decides to sell, has a wider commercial audience - people who will train him AND people who would want to use him in the team. (The above benefits would apply to other trainee's, and these are benefits as well).
My recommendation is that - at some point in the next 3-4 seasons, you will need to train secondaries at some stages- absolutely. definitely. For me though? id train majority primaries.
So yer, its a choice - there are pro's and con's to each - im just merely stating some of the cons and pro's of my suggestion. Nothing wrong with, nothing wrong about training secondaries either, its a choice for the owner to decide with as much info as we can all contribute.
