In 5 on 5 be the player on the bottom left and when they start run around the player chases you and jump to the player throwing the ball.
When you chosse 5 on 5 chosse blitz everytime then press B to change to the person next to it to sack the Quarterback.
To do a "juke", you just need to press B when on offense. This will help to shake off opponents and fake them into going in a different direction.
When they kick it off go to the left with the ball up the field for a touchdown.
