Everybody knows training effectiveness relates to trainer level, age, height, relative skills, etc, therefore all of us is trying to purchase relatively young player (e.g. 18 year-old) instead of elder player (e.g. 24 year-old) to enhance the training result, however, the cost impact is large if we tend to do in this way.
Now i have another thought to purchase an elder player (e.g. 24~27 year-old), but they are newbie in this season (player ID: 12xxxx) to save some cost. But the point is, whether no. of seasons played affecting training result?
Player A: MVP potential starts his career at 27 year-old
Player B: MVP potential tarts his career at 18 year-old
If player B will still have popup until 30 year-old (12 years long), shall player A will have popup until 39 year-old?
