I am using the above file for college and
this file for NFL.
I have not updated the NFL file in a while. I might get back to it once the season starts. It is more stable than Rate Sports' file (no crashes and it can be taken online), but it's only 11-players per team at the moment and the play-by-play names are wrong.
There is a thread for that NFL file on the first page of this forum that goes into more detail. It's called "NFC/AFC South online enabled roster file (Work In Progress)"
