Nero & Zoot, I think you may have your gameplan adjustment speed too high. The default is just 5 - the higher the value, the more likely your team is going to use more medium and long situation plays if you are doing poorly or go to more short yardage plays if you are doing well (checking Zoot's game log I see his game started with some very short running plays, which combined with a higher adjustment speed will send him into passing situations with shorter and shorter distance to go. Miami on the other hand had several long plays to start the game, which probably sent your gameplan into using more short yardage plays).
FF, I checked your playbook 3 minutes before the sim ran and compared it to your current playbook and it is identical - which, if you had made changes to it that you don't see now, makes me wonder if it's saving. Could you do me a favor and go back to the home page after setting your gameplan, then back to the game planning screen, and make sure the plays stuck?
I did verify that no one had their game plan AI'd this week.
