We can give this a shot but it will have to be monitored as we go along. Knowing that some owners prefer some eras over others, when an owner has more than one team in a Round, I usually will try to separate their teams based on era. For example, if you have three teams in Round Two, you could end up with a team in League 2, League 9 and League 15. It doesn't always work out perfectly but it's the best I can do.
If you want to trade spots with someone who already has a team in the league you're trying to get out of, that's another thing I'd have to look at as well.
If you have 15 teams or less in Round Two, I'm keeping those teams in separate leagues. The only owners who will have more than one team in a league are the owners who have more than 15 teams in the Round - there's nothing else I can do about that.
Once the 15 Draft Boards are set up and ready to go, I'll open things up for 24-48 hours for anyone who wants to try and figure out a swap. Once I see that all chatter about trading spots has subsided, we'll begin the drafting. Once drafting begins, there will be no trading of spots.
