Each of the 32 teams in Madden 13 are assigned a paticular scheme - and oddly - this scheme appears to be static (should not be surprised that madden doesnt allow us flexibility here) - but i found away to change the scheme without having to officially change it in the game...

What you need to do is just know the different types of players that make up the various SCHEMES then apply those player type changes to your team... your personel that you have on the field dictates the SCHEME you are in - not the title of the scheme on some obscure screen deep inside CC
