Get Madden Tokens easier:

Change the game difficulty level to "All-Madden". Then, modify all of 

the human stats (Example: O-line Pass Blocking, QuarterBack Accuracy etc.)

to the maximum at the AI settings screen. After that, change all the CPU 

attributes to the lowest. Set the quarters to 5 minutes and select a team 

with a good running back (example: Washington or Seattle). As the CPU stats 

are low, still difficult to pass. You will be able to rack up well more than

500 rushing yards. You can get over 700 Madden Tokens per game in this way.
