Hint: Easy crib credits: Create a team of the worst players ever, then play them with the NFL team or a team of your choice. The opposing team will be easy to crush under any difficulty setting.
In franchise mode and you are about to play a game, go to "Gamecast Live". Let it simulate the game, then take control in the fourth quarter before time runs out. You will be credited with everything that happened during simulation, and everything you did while actually playing.
