With v1.07 of the current roster update released and 2001/2002 completed (although I'll probably go back and add some free agents, fix up some ratings, etc), I've started work on the 2000/2001 roster patch. There's more players to create this time around (I only needed to create 5 missing players for 2001/2002), so it will take a little longer.
So far, I've done all the Atlantic Division teams (Boston, Miami, New Jersey, New York, Orlando, Philadelphia, Washington). So the patch is basically 24% complete, not including additional free agents, deleting players who entered the league after 2000/2001, double-checking and correcting, etc.
The earliest rosters I could find are accurate as of November 6th, 2000 (about a week or so after opening night). It's still basically opening night rosters, but probably with a couple of players who were picked up in the first week of the season.
Can't say when it will be finished, but it's progressing fairly quickly, so I'll do my best to get it out ASAP.
