Easy first down
When you are on offense have go down to traps. Then snap the ball and press [A] for that receiver. You should get an easy 30-40 yards.
Glitch: Player positioned wrong
When you are on defense, at the end of a play just before the game goes back to the play call, dive and hold [Down/Right]. When you return to the play call, keep holding [Down/Right] until the game takes you to special teams. Press [C] and select "Field Goal Block". Continue to hold [Down/Right] until the play starts again. The selected player should be laying down or kneeling and will remain so until you dive or jump.
