That makes sense, but I can see how it could be a problem.
Say I want to accept an uneven trade, and I'm willing to drop someone if it goes through. I don't want to drop that spot if it doesn't. It should be like waivers where you can specify a guy to drop, and if it doesn't clear, then you still keep the guy.
