Some Tips for getting this achievement:
- Off-ball everything: I know more experienced 2k players think this is lame, but off-balling is the way to go to play the best defense simply because of the jerky movements of your controlled player. I found it best to off-ball Shooting Guards, which you can do by pressing
and then
while on defense. If the opponent gets it to the SG, press
then
to switch to guarding the PG. (basically off-ball whichever guard doesnt have the ball)
- Don't rise up groupings. Stay in Freshman. To rise up you need to win 3 games with a Tier 1, and 1 game each in Tier 2 and 3. Don't do this. Continue using Tier 1 teams. They're better and your opponents won't get that much harder.
-Play as the Lakers. Despite being average in real life, the Lakers are ridiculously unfair in 2k (specifically LeBron). Literally all you have to do with the Lakers is get the ball to LeBron, run towards the baseline and then curve towards the basket. LeBron has enough speed to get around the defense and finish almost every time. And on the rare occassions he misses, AD or Deondre Jordan get it about half the time. Eventually LeBron will need to sub out, but if you play good enough defense you will either have a big lead or the opponent will have left already. In my 10 wins, I think I played more than a quarter 3 times.
This achievement is easy enough if you stick with it. There are enough people that on-ball everything or are just bad that you can probably win half of your games with little effort. I think it took me 15-16 games to get the 10 wins.
Good Luck! If you have any problems with this guide let me know in comments what I could do to improve it.
