I support you on this. Don't listen to those who force training, thus making 21-years-old-or-so players with 100+-or-so salaries. You're still not up to handle those players.
I'm "forcing" training. I drafted a 18y old with all respectables in guard skills and he received balanced one-position training. At his 21 years, his projected salary is 40-45k. Is this really so much to bear, provided you promote in the meantime?
From your negative connotation when talking about one-position training I'd say you either had some bad experience yourself or you didn't train properly. I will give you another example:
(13647772). He was being trained by a D.III team (he was in my league at that time) and didn't train anything else but IS, ID and RB; secondaries were all Atrocious except for JS which was at Pitiful. When he turned 21, his salary was 180k. Problem was, his manager didn't know how to manage his team wisely and he bankrupted.
You get a rookie with higher potential, you get a dearly bought trainer, and you force, force, force. In three or four seasons, the guy simply grows useless, as his salary grows to an unbearable level. Eventually you choke, you can't sell him for much money as rare managers won't them, or you could, with some luck, if you're training for money.
It seems like this happened to you. Sorry to brake it down to you like that, but if you don't know how to train properly, don't go around telling others one-position training is dangerous or useless, because it's not.
If you are in D.5, here is the recipe to promote in two seasons with one-position training if you are training guards:
- buy three 18y olds with P.Allstar potential - you can get all three for under 200k
- buy old and cheap PF and C, so you don't pay much for salaries
- first season train, train, train and aim for 5th spot so you don't pay any salaries in the offseason
- 2nd season, your trainees will have around 6-9k salary each, which is perfectly manageable for D.5
- aim for playoffs and few weeks before playoffs buy good PF and C with money you saved
- win the league, go to D.IV where you have a team that can compete with others; your trainees will have salaries 12-15k which is again perfectly manageable for D.IV team
Repeat the above steps, but replace "18y olds" with your existing trainees, and in two more seasons you are out of D.IV and promote.
This is a quick and efficient route, but it may not be enjoyable for many teams.
