NBA 2K12

Choose Miami. Set game time to 1 min. quarters. Adjust sliders on offense and defense for you, the user, to 100 in every category. Adjust computer to ZERO in every category. Pick a 14 game season and sim. Make sure each playoff round is one game. All you have to do is play 1 min quarter for 4 games in the playoffs after you sim regular season. Took me maybe 30 minutes or less. I went 12-2 simming as Miami in reg season and did not accept any trades.

U can use your own sliders and 1 min. quarters.

the fastest way to get this achievement:

Choose Miami, Boston or any other really good Team.
Adjust the sliders to 100 in offense and defense for the user Team and to Zero for the Cpu.

Season with 14 games
Playoffs best of 1
Simulate the Season
Now choose to play the playoff match... Score 2 or more points and choose quit and sim to the end
also do this for the next rounds and the achievement pops up after u come back to the playoff screen.

Sorry for my bad english but i hope this can help.

For the best record achievement and this one you can just go into a game then hit start quit sim to the end of game and it will count as a game played. Once you get to 30 make a save, then just turn auto save off sim to the end of the season and hopefully youll get the best record. If not then just reload your association file. Then do the sim quit thing in the playoffs as well to get that achievement. You never have to play an actual game. As long as you picked a good enough team, you'll have no issues with getting this.

It was pointed out to me that for some people, 30 games did not count. To be safe, its suggested that you start "playing" 31 games.
