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.
