Cause Human Opponent to Miss a Free Throw:
When you are playing a real-life opponent, and they are about to shoot a free throw, rapidly tap [] and your opponent's controller will vibrate. If you time this well they may be caught off guard and press X at a wrong time. Keep in mind that your opponent will probably catch on after a couple of tries and no longer miss. Also, this may not be very successful on easier difficulties, where a free throw is extremely easy to make.
