LCD = Let Coach Decide
SFDC = Strictly Follow Depth Chart
I think the LCD option should be excluded from the game. I think this option allows users that don't even care about the game and log in once a week or less to be able to win games easily, without any effort. I think setting up your team for the game is a basic thing in a manager game and it has to be done by the user. The coach already does a lot even in the other substitution options, we don't need an option that gives him complete control.
I also hate that common phrase growing among BB users "if you want to win then play LCD, if you want to have an efficient training than play SFDC". Unfortunately I came to conclude that this phrase several times is true. And I hate it! I think this is really bad. You should win thanks to your own efforts, not because the AI of the game allowed you to.
one small example: The current champion in Brazil seems to be in auto-pilot (playing normal offense and defense, and LCD). He went unstoppable all the way to the title, and we couldn't do anything about it (like me, effortless trying to beat him in the finals using SFDC). Now the new season comes and my cousin with his beginner's team and knowledge of the game, decided to "see wtf is this LCD option". And then he goes and beats the champs by 12 points playing away.
