I'm starting an NBA sim league using the game "Fast Break Basketball" beginning during the 2002-03 NBA season. I created the league file myself and it is based on rosters as of October 2002.
Here is a link where you can view every team's roster that has player ratings and salary: http://beyondthearc.epizy.com/rosters/
The West is stacked with the Dallas Mavericks (Dirk and Nash), the Lakers (Kobe and Shaq) and the Spurs (Duncan, young Parker/Ginobli). Then you've got stars like Iverson and McGrady in the East.
It's also the year before the LeBron/Wade/Melo/Bosh draft.
I plan to sim daily and at that pace we should finish a season in about a month of real life time. We can go as many seasons as there remains interest and I hope it lasts a long time.
It's all run through a message board forum, which can be found here: https://beyondthearc.jcink.net/index.php?act=idx
It's quite fun and a great community to be a part of as a basketball fan in my experience. I hope you'll join if you're interested, as 23 of the 29 teams are still open.
The rest of the rules for the league are explained in greater detail on the forum. I used other similar leagues I've seen to sort of form a skeleton, but if you join I'm open to any suggestions you have on how to make it better.
Hope to see you there!
