The AI is pretty good at picking up situations like 4th and 2 when you're down late in a game... I know you're new, so what I would suggest is watching a few games and if the computer screws up your game, you can make a rule to rectify it.
Under Gameplanning/Misc you can adjust your 'Hurry Up' and 'Slow Down' modes, I don't know if stumbled upon that...
That being said, it is EPIC that you've been creating rules for situations, and you haven't even been here a week! That kind of commitment will take you to championships, my friend!!
