My friend get the tips and info on tweaking and do your thing but build your team how you want it to be, you can get advice all day, but bottom line you have to play with this squad, so build it for what you want to do, basically alot of coaches have a right and left side back a straight speedster back and a blocker type, but also you must consider what style and weight this team will be used in. Advice is cool and here youll get alot of it, but do your own thing so do some resarch (look at FF.com posts they will help) and Matriculate the ball down the field!
