NBA 2K11

Go to The Association mode on the options screen and choose a team. As much as I don't care for the Heat I picked them and put D-Wade a PG & L-James at SG. I set the difficulty to Rookie and 2 minute quarters.
This can be done in no time. I am not sure if you can get it on 1 min quarters, but I can assure you 2 minutes works perfectly.
The Achievement will pop up once you win your 5th game and click "quit" game after the player of the game is announced.
That easy.
Also before you start your 1st game where it gives you the options to customize, make sure you do a season at 56 games and not 29 so you can also get the 30 games played achievement with the best record of the season.
I also set the Playoff matches to 1 round games and not grind it out for a 7 game series for the NBA Championship achievement as well.

Start a New Association, picking any team that you wish. The only important setting in this setup screen is to make sure the "Quarter Length" is set to 1 Minute.

From there, start your franchise and play the first game. Before the game begins, press start and change the following options:

Options > My NBA Settings > NBA Rules > Shot Clock OFF
Options > My NBA Settings > Gameplay > Difficulty "ROOKIE"

And now change the following Sliders:

Offense > 3PT Success > 100
Defense > Steal Success > 100

After changing these, you should make just about every 3 point shot (with players that have decent outside shooting) and you can get just about every steal you attempt. Just score a few baskets (go up by 7 or 8 points) and then hold the ball and run out the clock. Repeat for 5 games (the sliders/rules that you set should save for the next game) and you have the achievement.

set game length to 1 minute quarters and change the sliders in your favor and just play the five games,if you cant win five in a row with the sliders in your favor then you should not be playing this game.
