Well, according to the this link:

The Dolphins have 91.2 million commited to the cap for 2007, but only 35 players signed. From what I can find, the following Dolphins will be free agents: (just to name a few)
Cleo Lemon - QB
Darian Barnes - FB
Patrick Cobbs - RB
Wes Welker - WR
David Bowens - DE
Keith Traylor - DT
Vonnie Holliday - DT
Jeff Zgonina - DT
Kevin Vickerson- DT
Donnie Spragan - LB
Jeremiah Bell - S
Traveres Tillman - S
Norman LeJeune - S
John Denney - DL
Jack Hunt - S
Dan Stevenson - OL
Toniu Fonoti - OL (could only find that he was signed.)
Eddie Jackson - CB
Kendyl Jacox - OL
Donnie Jones - P
Shane Matthews - QB
Robert McCune - LB
Damian MacIntosh - OL
From where I am standing, You've got some big holes on the lines to fill. Heck, your entire starting D-line, with the exception of Kevin Carter, are free agents.
