NFL 2K3

Power hit:
Press L + R to power hit your opponent.

Use this special move to plow through the defense. While running the ball, hold L + R. And the runner will shoulder charge the opponent, and knock them on their butts. This is very useful when you need that extra yard.

Spoken created player names:
Enter one of the following names for a created player to have them announced during a game.

Hint: Prevent opponent from selecting desired play:
When playing against a friend or friends, use this trick so they cannot choose a play, or more accurately, the one that they want. Make sure you select your play before your friend(s) do, then press Start to pause game play. Their play book menu will go back to the beginning, forcing them to start picking the play again. Keep doing this until the play clock runs out, and they will not be able to choose their own play.
Will Smith.

Hint: Predict plays:
Look at the offensive tackles used by the CPU before any play is run. They will either be in a two point or a three point stance (their hand will either be on the ground or on their knee). If they are in a two point stance (hand on knee), it is either a pass play or a draw. If they are in a three point stance (hand on the ground), it is either a run or a play action pass. This works all of the time, and the CPU rarely uses play pass or draw -- you can almost always guess what play they are running.
Parker.

Note: You can also predict a human opponent's play, even though they hide it, by watching the position of the defensive ends. They are the same as when predicting the CPU plays.

Hint: View end of season highlights:
To see highlights from your team's season, win the Super Bowl in franchise mode. Approximated highlights of your rise to glory will show while the credits roll.

Hint: Get the ball on kickoff:
Whenever you kickoff do a onside kick. Aim on the opposite side of the other team, low. If done correctly, you will get the ball.

Hint: Onside kicks:
Press Start to pause game play. Select "Game Plan", then "Substitution", then choose "By Package". A list of packages will appear. The one you need is at the bottom. Now, go to "Onside Kickoff" (and not "Onside Kick Return"). A list of players will appear. You will need to select the correct one. Change the tightend into the kicker. Select one of the tightends and the game will ask for a replacement. Go down the list, find the kicker (K), and select him. Exit out of the pause menu. Then, select "Onside Kick" instead of "Kickoff". While kicking, position the arrow all the way up. Instead of a regular onside kick, position the kick not all the way to the left but almost there. When kicking, make sure the power bar is filled. The works almost every time.

To always get the ball on onside kicks, in game mode go to the options screen select "Penalties". Turn off the "Illegal Onside Kick" option. Before you pla,y go to "Substitution" and then "By Package". For "Onside Kicks", replace the tight end for the kicker. When you onside kick, keep the arrow all the way to the right and power at half.

Hint: Run faster:
When running with the ball, rapidly tap Speed Burst instead of holding it.

Hint: Funny commentary:
Choose a passing play and take the ball. Fade back for a long time and the announcer will say, "I've heard of fading back but this is ridiculous!" or "What is he doing?"

Hint: Getting rid of the best teams:
In season or franchise mode when playing in the NFC, it is easy to get rid of the best team on the game, the Rams. When you look at the schedule, check if the Rams' game is before or after your game. If their game is before yours, simulate up to your game (do not play your game). If the Rams won, quit and repeat the process. It should take about five times until they lose. If their game is after yours, just play yours then save the game. Then, simulate. You do not have to use this trick every week of the season -- just up to when they lose nine games. This trick also works in the AFC with the Patriots. Note: It is better that you actually play your game then simulate for best results.

Hint: Broadcasters announce your last name:
Go to "Roster Management" and select "Create Player". Then, type in your player's first name and enter any pro football player's last name. Put him on any team as a starter in any position, The broadcasters will say his last name.
bill gannon.

Hint: No first name-announced:
When you create a team in the Roster Management section, and play with the team, the announcers will only say a player's last name. For example, when Brett Farve is shown in the Offensive Lineup, they will only say Farve and not Brett Farve.
Jerry Schmidt.

Hint: Change attributes:
You can go into roster mode and change attributes. Highlight the attribute that you want to change and select it. Choose "Change Attribute" and use the numbers on the top of the keyboard to enter the value (0-99) for that attribute. You can use this to make your team completely unstoppable, or make your opponents unworthy.
Parker.

Hint: Get lots of draft picks:
Go to the trading block and put down your three top players. Then, play a few weeks of the season. When you go back, there should be offers from teams. The more, offers the better. Put down your first and second picks in each trade offer. then leave the trades on the trading block. Go to the regular trade screen and trade away your first and second picks now for whatever you want. Go back to the trading block and view each offer. Your draft picks will still be in each offer, and you can trade them repeatedly.

Hint: Additional player creation points:
This trick will give a player additional points when creating a halfback or a fullback. First, go to "Player Create" and select a halfback or a fullback. In the point distribution screen, select the "Speed" archetype and distribute points as desired. When done, save the new player. Return to the main menu and load the roster file. Return to "Player Create", select the player that was just made and go to the point distribution screen. The archetype listed will now be "Power" and there will be an additional 99 points to improve the player.

Old team with modern logo:
Press L and R to cycle through the teams until you see either what looks like a man in a two point stance (1985 Patriots) or an oil rig (Oilers logo). Watch the beginning FMV sequence, and if they show the coaches they will have the team's modern logo.
