That's not how sign and trades usually work. If it were to happen, the Wizards would approach us to see if were willing to do a sign and trade so they can get something back in return. So in effect we would be doing them a favor by doing a sign and trade, because the only reason they would be asking for one, is because they wern't going to match, and thus lose Porter for nothing. So in that scenario, we wouldn't be taking back any of their junk. We'd only be getting Porter, and then sending them Koufos and/or Malachi. Just an example.
