Here are some deals I threw together that were accepted by BTV. I'm not saying I am for all of them, but the theory behind each trade is that was can lessen the return by taking on a contract the other team wants to shed.

Also, I would not be surprised if every opposing GM said no to these deals. In some of these deals, I'd offer more than listed (needed on the BTV site) or take back one less piece,
