Create a team with very bad players, then play them with a team of your choice. The opposing team will be easy to beat on any difficulty setting.

In franchise mode when 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.
