Original NFL names/nicks

[Warhammer]

I have tried changing my .fgr .fni and .fcy files from my MP back to my SP game, but I keep getting all the names and nicks from my MP file, is there anything else I need to change?

I have even tried letting the game create the files per another thread, but I keep getting the same names.

They are stored in the .fni file (team names along with division alignments and city indices) and the .fcy file (city names and abbrevs). If you are still getting the MP names, then you're SP files are corrupted, perhaps with a copy of your MP files.
