In Dynasty Mode you recieve MVP points periodically for accomplishments. Assemble a team you feel is good enough to simulate to the playoffs (hint: Yankees). Simulate the season up to the second to last game and then save the game. Once you have it saved, simulate the last game and move into the playoffs. Generally, you recieve anywhere between 5000-9000 MVP points for making the playoffs. Save the points onto your profile when prompted, and then exit the Dynasty mode without saving. Repeat the process and you'll notice that every time you simulate into the playoffs you're saving the points and not your progress. Do this about 20-25 times and you'll have enough points for all the rewards.
