Set up a 2 minute halves game on two controllers (your team on controller #1 vs. an opponent on controller #2) and lower the FT difficulty setting to 0. Whenever your team gets the ball, press the BACK button on the second controller for an intentional foul. After 7, your player will automatically go to the line. You may want to practice FTs on All American difficulty for awhile, they are much harder than the other levels (all timing). Pull the RS down until the ball reaches the top of the shooter's eyes, then push it forward. Try to make the down-and-up motions as fluid as possible. Once I got it down, I never missed.
