The only setting that matters for this achievement is the quarter length. 5 minute quarters are minimum for this achievement.
Other then that, you can turn off all NBA rules, and turn User/Computer Sliders up/down.
With sliders turned up, you can dribble out the clock. Around 5 seconds make your way to the 3-point line, at around 1.5 seconds left shoot a mid range/3 pt shot. As long as no time is left on the clock when the shot goes in, the achievement should pop.
If you are having any trouble with this achievement, call a time out around 15 seconds left, after the time out save and quit out of the game. When you reload you will be coming out of your time out. If for any reason you are unable to make the shot, dashboard out of the game and retry.
