i just found a way to assign names like "Lights Out" or "Mr Clutch" to players whose names are unknown to the game.
All you need is REDitor II and a roster- or draftclassfile.
1)Change the playertype of the player of your choice to 5.
2)Start the game and open the edit player tab of the player/s whose playertype you just changed
3)Select any nickname you want
4)save you changes
5)Now you can set the playertype back to 4 (usual). If you don't do that your player/s will shot up in the create player menu as well.
6)Enjoy the result in any game in the future
