*NOTE* All team/player achievements can be earned with a controller on the other team. It is much easier this way. Also remember to put the game on rookie, and edit the sliders so that the home team (User) is boosted, and the away team (CPU, or Player 2) has horrible sliders. If needed, put the quarters on more the 5 min.

Make sure you adjust the sliders to make this very easy. You can get this while going for 15 Steals Trophy, just get a steal and go beyond the 3 point line and make the shot. If you adjust the sliders, you will make the shot pretty much every time. I found shooting with 
is much easier than the 
but just use the one you find more comfortable.
When you are going for this achievement, don't shoot any bad shots to try and get rebounds and you will also get 3-for-All Trophy when you finish the game.
The achievement will unlock right when you hit your 15th shot. You can use two controllers.
