I have searched everywhere and can't seem to find a manual or literature that explains some of the features in the game settings. Such as "Unlock Depth Chart" or "Use Modern XP Rules" ect... Anyone know where i can find this information. Thanks.

Unlock depth chart allows teams to play players at any position in the depth chart versus just offensive/defensive positions.

Use modern XP is where they moved the XP line back a few years ago.
