I agree with the rest. Don't trade Green for Fiedler straight up. He gets the better of the QB's and eliminates his problem.
I would go for the second trade if he accepts.
I might make the trade if aanother player was offered that has value to you. The longer you wait will force him to do something, either with you or with another team. He is going to make the deal that is the least damaging, so you need to protect yourself the same way.
