I'd assume WFs usually stay wider than SSs.
Yeah. When you edit a players position, you can see the specific sections designated for CF/SS/WF.
There's nothing particularly obvious in how the roles differ. That is to say, by changing a players role isn't as influential as changing that players position or individual tactics. Maybe it does make a difference but it's so subtle and well-coded that you don't notice.
SS pro's: Drops deep allowing the ball to be picked up and supplied to CF or WF. Can drag defenders out of defence creating space.
SS con's: Deep sitting midfielders can get in the SS's way. Can leave CF isolated.
WF pro's: Gives good width and stretches defences. Great for fast-paced counter-attacks. Useful if you have a commanding post player.
WF con's: Less useful against teams sitting deep. Leaves CF isolated.
