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.

During a game, turn off the penalties and when your on defense, go near the QB on their side. When they snap the ball, sack him for lots of crib credits.

To earn some crib credits, simply browse the game's menus. The best menu is the "Game Manual" in the "Extras". It tells you how to blitz defenders, assign tight coverage, juke, etc.
