To attain this achievement, make sure that the opposing team does not score any points in the last two minutes of the fourth quarter. I would just make the opposing team's shots' and lay-ups' success as 0 in the game sliders.
To make this simple, and to make attaining other achievements for this game easier, I recommend taking the time to edit the sliders to your favor beforehand.
When you load the game and enter the menu, look for the tab that states "Options." Once there, find the tab that says "My NBA Settings." Next, simply go to the tab that states "Game Sliders," and put the attributes to your favor as well as downgrading the computer's stat.
When you have finished, just back out and go to a quick game, in which case the game will automatically save the sliders for future games. To disable or reset the sliders to how they originally were after you have attained your achievements, just go back to the sliders and it will give you the ability to customize it to default sliders.
To get this achievement, you can just play a quick game with either a computer or two controller method. But note that if you are playing against a computer, you cannot switch teams or sign in a controller or the stats will be disable. Same as the two controller method; once the game starts, you cannot switch teams or sign out a controller when already playing with a friend.
*Note* You do not have to finish the game to get the achievement. You just need to get the necessary requirements during the game. Once you get the stats you need, the achievement will pop up.
You can change the difficulty to Rookie but it isn't actually necessary when the sliders are in your favor. If you are going for other achievements, I recommend changing the time limit of the quarters to as long as you need.
Finally, it is slightly annoying when the player you are using magically gets substituted. In the begging of the game I highly recommend going to the menu, then "Coaching," then "Coach Settings," and putting the following to MANUAL: Timeout, Substitution, Late Game Fouling.
