I don't think the basic rules of football that you so eloquently posted are what's stumping us, it's how the play-calling works and what appropriate strategies to take for a given situation. What the hell is a dime play, what's the difference between weak and strong I, what do you use the special teams playbook for, and how often should you run versus pass, etc. All those sorts of questions are what stumped me when playing Madden at first until I started watching how others played.
