I agree with the basis of the proposal but precisely one of the things that I liked most about the game is discovering that a player had to be used in certain positions to increase his qualities in a certain skill.
Contrary to what you say, it is something completely real. For example, Pau Gasol acquired his passing and dribbling skills playing as a point guard for Barcelona despite being the tallest on the squad.
He did do that in the lower categories, not once having risen to the first team.
That's why I like your idea but related to another that I have proposed, which is youth teams.
(323660.1)I think that the player's initial training is very important and that once he reaches the elite the player continues to evolve but more in tactical concepts, game vision and above all experience but at 24 years old he does not know how to shoot from 3 or give a pass You are no longer going to become a master of that.
On the other hand, that a national team has to play official matches with improper third-category players, either to avoid exhausting the starters or to train them when they are already quite old, seems crazy to me without any sense.
