This trick works well in a two player game against the CPU. When you score, have your friend select point guard and leave him at your end of the floor. You play 4 on 5, which is not difficult, especially when up against the CPU. When you get a rebound, press R2 to send the ball to your friend, who has stayed at your basket, and dunk it or perform a lay-up. Do this repeatedly to get maximum points and down the opponent.
