Easy sack
Turn off all penalties, then get right next to the QB when you play defense. When he hikes, sack him, or wait until he drops back to get more sack yards. This is also an easy way to win the game (assuming that you score at least once and you don't screw up the sack technique somehow).

Always Get The Ball
Use the following trick to always get the ball start a game. On any play, if your opponent has the ball press Start and go to 'Options'. Choose 'Crib Cheats' and turn on the 'Always Fumble On A Tackle' (if purchased) and turn off penalties. When you and your opponent select your plays, go behind the QB, If you touch anyone, you will be flagged. When you tackle him and there is a fumble, recover the ball. When you have to select a play, press Start, go to 'Options', select 'Crib Cheats' and disable the 'Always Fumble' cheat. When you begin the play, your opponent will not tackle you and cause a fumble. Repeat this as desired.
Beat The Salary Cap
Beating the salary cap can be frustrating with created characters. Instead, go to the roster for your favorite team, find the third string position player, then just edit his name, stats, and appearance. By doing this, your player will be rated 100 overall, but still be paid a very low salary.
Touchdown Pose
When you have bombed on an opponent and have no one around you while running towards the touchdown, slow down (by slightly pushing the Left Analog-stick) and your player will stop at the one yard line and pose before scoring.
Strange Sounds
Play at either the Falcons or Seahawks home stadium. You will hear bird sounds after a big play.
