Now that the season is over, I have released into Beta a new feature - Gameplan Rules. The tab is located in the gameplanning screen next to the offensive and defensive gameplan areas. This feature will give you some serious control over the plays called by your team in very specific situations; the game will call a play from your rules if there is a rule that matches the situation, and will fall back on the standard game plan if not. Things like going for it on 4th down in certain situations can be programmed into your game plan.
I don't want to go into too much about how it works because I want to see how intuitive it is to use, or if I need to add some additional instructions or even change the way it works. If you want to play with it, let me know how it works for you. We'll see it used in the upcoming preseason games.
