Learning a new position by playing at it

[KenoticFC]

rather bad idea
Let's say that we want to "teach" our player a new position by using him there.
That means that in a whole season (probably) we must use him playing oop.
I cannot risk that but a tanking team with anything to loose, can build easily a team with 3 positions.

I suggested this some time ago and my idea is for the player to get more experience when playing in the position you already CHOOSE to train him. I don't think that he means that players playing outside their position automatically train for a position without our consent.
