Are you sure about that? If you mean roster files for 2K4 I've posted them at least twice from my own files.
Posted from the online roster Jan 2 2004 or something like that and its still up someone ask me for it sometime ago and I posted it here at "OS...Da Spot" so look again bro it should still be there.
Update: I just checked bro the file is there and its been posted twice in different places about 2K3/K4 rosters by yours truly so enjoy and read the threads carefully.
P.S. Read the thread carefully like I said because I did mention that I had these files in my personal data base(For 2K4) and online DLs from the online account (XBOX LIVE)
Holla Back y'all
