Just trying to figure out the rules.
It appears that you are new. So I would like to earnestly help you so you understand what it takes to fill a league.
1. Sell your league. Get people excited. One line descriptions don't sell the sizzle. FIND A HOOK. The two season thing might be interesting with an expanded player pool, but you don't have to do that. Find a way to be different, and have a team that will be a fun concept to build.
2. Good Idea (which I think you have the beginnings of)
3. Clear Cut Rules. I could have put my team in and I wouldn't have known about the question I asked, the salary cap, or whether or not clones are allowed. Plus I don't know if you are allowing rookies. This is a huge deal in drafting because then I will know whether I need to draft close to the 19,680 Mins or 18,000 Mins.
4. Lastly, and least important...gain a little more cred before trying to fill a league. You have been playing in an OL for about a week now, but no one knows you in the theme league universe. Play some other theme leagues before trying to fill your own league. You may have a 100 Mil Cap on this league, and you think that a starting lineup of Magic, MJ, Bird, Duncan, and Wilt at their most valuable seasons is the best team to go with, and then you are going to get your *** handed to you by someone with a Kidd, Brent Barry, LBJ, Rodman, Wilt lineup that focuses more on unique skillsets than brute strength in terms of salary. Chances are you may not have learned that in this sim you have to throw away much of what you know about the NBA.
For all I know you may be a long time player that felt the need to switch ID's, and if that is true forgive me, but don't think that people are going to flock to your league if you haven't first done the same for others. Again I am not trying to be a douche, but as a long time player I tend to understand the atmosphere here. If you can crystalize the first three things I mentioned, the fourth may not be as big of a deal.
