As the first version, i suppose, we should make a roster, containing 2 extra teams: NLSC Administration and Top NBA 2K10 Contributors.
Why not less than 2? Because most of us are relatively small guys, and i'd like the roster to be quite realistic (real height, weight, skin tones, bodytypes, etc.), so these 2 teams will be able to play against each other.
Why not more than 2? Let's make 2 as the first version, and then we will have an opportunity to make other 28 teams to start Association. 30 teams require 360 players (12 each), so it's quite a number.

So, the rosters of the first 2 teams:
NLSC Administration:
Andrew
Jae
JaoSming
Pdub
Andreas Dahl
dragon@4Q
Kris
Lean
Qballer
Doobie (?)
Top Contributors:
jor1980
Vl@d Zola Jr. (sorry for adding myself to the list, but i think, everyone would agree, if not, so i will remove myself)
aloncho11
inbar
STOMPTHECOURT
Kova19
Tha King
*+ 5 PlaceHolders*
These 7 guys are those, whom i personally would choose as some of Top Contributors. Of course, i will add only those, whom the majority will consider to be the most deserving, so there are 5 placeholders more + the first 7 can be replaced. We will be able to add other guys to next versions, which will include more teams.
I will write more details within some next days, as now i'm a bit busy and it needs to be thought over more.
For now, just comment and make suppositions about the idea.
Also, i would like to know the opinion of respected guys about the roster of the second team. But, please, don't propose to include guys, who mainly develop their projects on other forums (baballs, nbajam, etc.), as we will be able to contact them later and add 2-4 teams from each such a forum to the roster in future versions.
I take all the responsibility for this project, though, possible help is always welcome.
