Kevin Carter, Randy McMichael, Seth McKinney, Jeno James, Bennie Anderson and Joey Harrington were all cut, not free agents. So we get nothing for them. Same thing if Mare gets cut or traded. Welker was traded as well, so nothing for him, other than the picks we received in the trade.
That leaves only Zgonina, Morris, Minor, and McIntosh as players of "value" used in the formula to see if we get any compensatory picks. However, only McIntosh was really a starter type, so all their "value" could be offset by the "value" of the additions of Porter, Feely, Martin, and Schlesinger (and anyone else we may sign). So the Dolphins may get nothing.
