Ok, but which skills should pop? I think that choosing one by ourselves creates unrealistic advantage, because how do you tell to the player to valorize his experiences?
This is the way into not very good illusion about the game.
So it has to be done somehow according to his actual skills and might be good to get in there position where he played most of the time in past season.
For a Small Forward would then pop-up anything, for SG just shooting or passing and for PG just OD, HA, PA.
