That's one of the worst ideas I've ever seen put on this BB. You want to have the availability to try to deal with every team in the not just 16 or 18 or 11 or 12 in the tough leagues. It's never simple getting unmanged trades past, but, it's also sometimes getting trades made with active owners. That's part of the fun of this game. The final point of this is why would someone pick up a team in a league with 6 or more unmanged teams if they didn;t think they would have chance to deal with all the teams. Getting Rid of unmanaged trades is an absolutely horrible and abhorent idea.
