Before I begin I'm going to state that this tip only works if your created player in superstar mode is the quarterback for your team. In superstar mode before each game you get a number of practices. Just simulate all of the practices until you are at the last one. No play this practice but when you get to select the offensive play select the Hail Mary or streaks play. Then you get to select the defensive play, select it as FG block. This will blitz all of their defenders. So when the ball is snapped to you, you just have to quickly throw the ball to any receiver and he will get a touch down. Since it is the last practice you will have to repeat the play until you get the maximum amount of points it allows you to.
