For your MyCareer you will want to put the settings on Rookie and Casual, making the process of getting stats so easy, especially if you have already maxed your player out. It's suggested that you start this out in your 3rd season and leave the second season to the other MyCareer trophies.

Once you start the season, play the first game and get a high number of points, rebounds, assists, steals, and also blocks if you can. It is possible on these settings to score 100 points and have double-digit steals and assists, especially if your player is maxed. Once you finish that game, you can simulate a few games and then play another game and do the same, that way your season averages stay high. What happens is that your MyCareer replicates your performances in simulated games. Doing this will also get you  My Every Day Player and  My All-Star.

Once you have simulated the whole season and finished the playoffs, if you made it then it will be time for free agency if your contract is up. Based on your performance you will be offered close to a max contract or a max contract. If you are not offered a max contract, then negotiate with the teams to give you more money. A max contract is like 500 VC per game for 4 years. Once you accept the contract the trophy will pop.
