To Make Players Better
Dear Viewers,

To make your favorite team or player more talented, go to the main menu and scroll to the section that says FEATURES in the features menu you will see ROSTERS. Once you are at the rosters menu go to the team you want to edit. Select a player (one at a time) and you will see various options on how to edit the players appearance and other things including the players attributes. Select the ATTRIBUTES then go to each of the players skills and make them all 99. ( Or only some depending on the players position, for instance if you are editing a defensive lineman he does not need Kicking or punting skill.) To increase the entire team you need to increase the attributes of each starting player. NOTE: Increasing the skill of an entire team may be a very tiresome, woeful and timely experience.

PS: Thank you for reading this and I hope you all have success.
