Hey Vito
You have pretty decent trainees.
For the moment, the first two have salaries of about 10K (maybe slightly below) and third one about 30K. At the beginning of the next season not even the third one could qualify for U21 (and he'll be 20). If you keep training his inside skills for the rest of this season, maybe he'll meet the minimum requirements in that area, but his other skills are still lacking. You still need average (or mediocre) handling and passing. So if you're interested in a lower salary I recommend you get 1 or 2 more pops (or none) on his inside skills (if you have a good trainer, and he pops once per week) and then go with some handling or passing training. At this point the next pop on his inside skills (except SB) will have a salary increase of about 3-4K. The next one about 5-6K, and so on. Training his other skills (which are necessary as well) will have an insignificant salary increase. Go with what you feel it best for your current situation.
This is my main trainee:
Weekly salary: $ 6 001
DMI: 122100
Age: 18
Height: 7'0" / 213 cm
Potential: perennial allstar
Game Shape: proficient
Jump Shot: average Jump Range: pitiful
Outside Def.: inept Handling: mediocre
Driving: average Passing: average
Inside Shot: proficient ↑ Inside Def.: proficient
Rebounding: proficient Shot Blocking: strong
Stamina: average Free Throw: average
One position training with a lvl.6 trainer. For the next 3 weeks I'll still train his inside skills (should still get a pop per week), and the last week of this season, it'll be JS (maybe he'll pop in both JS and JR; last time I trained JS, he poped in 3 skills that week). I also need to cram some OD, HN and more JS.
I also aim to make him a good U21 player.
