But it couldn't surely affect, that the players I set as subs just were picked as starters for the game, right? The GE surely does nor defy the lineup roles that I have set as manager?
Based on my experience, when using "Coach picks from the depth chart" or "Let Coach Decide," the coach will substitute players based on their abilities.
If a backup is significantly stronger than the starter, the coach will let the significantly stronger backup start the game.
