I've been around the NBA SIM for quite some time now, and been involved in a ton of Progressive, Regressive and other continual-Leagues. Every single one of them has had instances where owners complained about tanking, Lottery odds, "dynasties", uneven trades, difficulty rebuilding, and anything else you can possibly think of. I've been trying to think of a way to minimize or even eliminate most of these concerns. By combining the "best" concepts (IMO) from several different Leagues, I've come-up with something I'd like to get feedback on - the Dual Era Double Progressive Partial Keeper League.
Each season would involve players from 4 NBA seasons. Two back-to-back seasons from two different Eras (EX: '64-'65, '65-'66, '87-'88 + '88-'89)
At the end of each season, each owner will keep exactly 6 players. (not including IR or optionally those with < 500 min.)
Draft order will be entirely random. It will be done using Random.org, by a non-League member or maybe Admin..
Draft picks may be traded for only the next draft, and not between the draft end and the start of the season.
With those rules, it should be a League where every owner tries to compete for the Title every season. It would be harder that ever to win back-to-back, let alone have a dynasty. Some certainly will not like the random Draft order, but that is a HUGE incentive to never tank, plus we have entire Leagues where players are removed from rosters randomly, draft order is 1/2 random, and player seasons are used randomly, that are great. With so much player turnover and so much "new" talent available every season, success one season doesn't have much to do with the next season any way.
I'm certainly willing to listen to input on this. If feedback is positive enough and enough owners seem interested, I'll give it a go.
