Easiest way to get this achievement is the two-controller method. Set the game to 2-minute halves, and set difficulty to All-American, the highest difficulty setting. Make sure you do not attempt any 3-point shots. Only take shots from inside the 3-point line. And with the second controller, as the opponent, simply don't score more than your primary controller. Turn the ball over on purpose.
All of the various tips that Verman360 listed in his solution are valid and will help as well, especially if you feel like earning this one against the CPU, but it will certainly be easier with two controllers. Just wanted to confirm that the two-controller method does in fact work for this and most other achievements in this game.
