Select the EA Sports logo at the menu. Note: It turns into something that looks like your "A" button when the pointer moves over it. Choose "NFL Rosters", then "Trade Player". You can make your team the best possible. If you run out of cap room, press B and choose "NFL Rosters" again then "View Rosters". Select your highest paid player and make him a bad player (rating 49 or less). Release them and re-sign them, then make him a good player again and they will be paid less than $1 million.
