Here's an easy way to fly through MyPlayer, getting all the achievements! I've done the hard part for you as well.
I went through the rosters of each team, lowered all the player's attributes to minimum, made their heights 5'3", and adjusted other things as well:
1. Gave them all 5 year contracts with no trade clauses
2. Made the majority of their abilities (dribbling, shooting) poor
3. lowered shot tendency on all types to 0 except for 3 pt shots, made that 99
I did this for EVERY team except for the Jazz, of which I did the opposite, maxing out everything, EXCEPT FOR THE POINT GUARD (because I am PG in MyPlayer).
I then created a MyPlayer PG, and after a few tries, got drafted by the jazz. Now you are on a team loaded with maxed out players, playing against ALL OTHER TEAMS with crappy players. The no trade clause for each player ensures NO PLAYERS are traded, as well as you don't get any of your teammates traded during your whole myplayer career.
I played as a point guard, and was able to get 9 out of 10 HOF requirements after the first season (yes, I got 1000 steals the first season). I only played the key games, 12 minute quarters on those, and got about 100 points, 40-50 assists a game, and 40-50 steals a game. At the end of the 2nd season, I got the remaining HOF requirement (2 conference finals one). Try to get as much as you can by the end of the first season, because each subsequent season will have less and less of the sucky players on the rosters.
I did have to go into about 20 games of the 4th season before I retired to HOF (to get the "10 million dollar a year contract" achievement and the "buy Michael Jordan dunk package" achievement).
This roster is entitled "min attributes roster." Check it out and use it for MyPlayer, Association mode, and Creating a Legend, it makes it ALOTTTTT easier.
Just please, give me a good rating on this download.
HOPE EVERYONE ENJOYS THEIR HOLIDAY PRESENT FROM ME!
