Learn to Shoot
Shooting in NBA 2K7 requires the player to pull back on the Playstation 2 (PS2) controller's right analog stick. This will cause the player to jump up into the air. Watch for the player to reach the peak of his jump and then release the analog stick. This takes timing and practice. If you shoot too soon or too late you will hurt your chances of making the shot. Therefore, you should practice this skill until it becomes second nature. The better you are at timing the shots the more likely your shots will go in and the better chance you will have at winning.
Tough Defense
A good offense is nothing without solid defense. On the defensive side of the ball, press the "X" button to switch to the player closest to the ball. This will allow you to control the player defending the opponent who has the ball. When you control the player, you have a better chance of getting the ball back and stopping the other team from scoring. Watch for your opponent to shoot or pass the ball and then use the "triangle" button to block the shot or the right analog stick to try and steal the ball.
Cheat Codes
The beauty of a video game is that when the going gets tough, the tough look up cheat codes and fight dirty. Use codes to help boost your players and make your team better. You can input the codes in the Features menu screen. For example, if you want your players to have maximum durability for the game, type in "ironman." For unlimited stamina, type in "norest." Typing in the passcode "rta1spe" will unlock the superstar team, a team composed of the best players in the game. You can use the cheats as a crutch while you master the basics of the game and turn them off when you feel confident enough about your own abilities.
