Madden NFL 2004 Cheats

Create a player without increasing any of his attributes.  You
can even lower them a little more to make his price as low as
possible.  Sign him for 7 years for next to nothing, then go back
into ‘create a player’ and increase his attributes to whatever you
want them to be without raising salary.  You can even max them
out, but how much fun would that be?

Great players that retire in franchise mode can return to be coaches. Wait a couple of years after your favorite star retires, and he will show up in the coaching free agent list to be signed as an assistant or head coach.

Note: This only works with controllers, mainly the
Logitech Dual Action. Press the four top buttons 6 + 5
+ 8 + 7 (Logitech Dual Action). Your player should
toss the ball almost to the other team, but they will recover
the fumble 98% of the time.
