Reach a desired level of MVP points to spend on a player, stadium, or throwback jersey. Use them to unlock a bonus, then save your roster. Do not save your profile. Instead, reload your profile. Your MVP points will be at their re-purchase
amount. Use them to continue buying as many other bonuses as desired.

Select dynasty mode and choose the Yankees. Turn off injuries, trades, rain outs, and budget. Set the difficulty on MVP. Simulate to the last game of each month. On that game, choose to simulate it (not quick sim; choose "Play" then "Sim"). Stop the simulation at the top of the ninth inning and choose to manage the remainder of the game. Do this for every month for the rest of the season. When the season ends, and you see "Advance To Playoffs", save the dynasty. Then, choose "Advance To Playoffs". Each time it will show your points earned.(about 13,000 to 17,000). Do not save after this. Exit dynasty mode, then keep re-entering and choosing "Advance To Playoffs". Each time you do this, you will get that same MVP point amount put into your profile.
