Let me say that if Chance Warmack is available at 12th spot, something wrong happened.
Top spots of this draft with decent QB have serious problems at OL. As Detroit, San Diego & Philadelphia come to my mind I see few chances that a stud like him could be available by the time Miami picks.
That said I think that a solid O-Line would allow the playmakers to shine.
Also we have to figure out what kind of additions & subtractions will be made before draft.
As today, few things are facts, but this is what rumors and common sense marks on Dolphins' own free agents:
OT Jake Long (UFA) - Money and not fitting zone-bllocking lead to assume he'll be plying elsewhere in 2013
CB Sean Smith (UFA) - There's a 50/50 chance he will be back with Dolphins
RB Reggie Bush (UFA) - Jeff Ireland is acting punk on him, arguing sophomore Lamar Miller will replace 2012 best player. Few chances of comeback.
QB Matt Moore (UFA) - Moore wants a chance to start, but that window could be closed as soon as May. I see him comming back.
WR
Brian Hartline (UFA) - FO wants him back and both side are dealing a contract that could make him wear his Dolphins' uniform for his whole career.
DT Randy Starks (UFA) - Some rumors say he'll be back and some others claim he won't. I think Dolphins will focus on playmakers and could lose him.
TE
Anthony Fasano (UFA) - Ireland loves his work ethics but is open to test the market looking for upgrade. I see him coming back in 2013.
S
Chris Clemons (UFA) - Aside of Hartline this is another pleyer in close talks to return. I see him as the surest return.
DT Tony McDaniel (UFA) - Tony is important part of defensive line rotation, but not a starter anymore, his return is somehow unlikely.
G Nate Garner (UFA) - Nate play well at every spot on the O-line, but somehow below starting class. His low value on the market should bring him back.
K
Nate Kaeding (UFA) - Kicker are replaceable in our days, I see him returning after testing the market.
CB Bryan McCann (RFA) - As any Restricted Free Agent, McCann has huge chances of staying, but as team will add important CB, lasting long is unlikely.
S
Jonathan Amaya (RFA) - Johnathan will be resigned at low price, and must prove his worth or won't be here in 2014.
LB
Austin Spitler (RFA) - Austin will see a standard 1-2 years contract offer in his hands and return to grow as LB.
TE Jeron Mastrud (RFA) - Jeron won't see a tender until last instant, as FO is looking for upgrades at the spot.
WR Marlon Moore (RFA) - Like Mastrud, Moore will have to be patient, as Dolphins will be fixing WR spot and could offer him a very low sheet.
On potential additions, the things is more complicated and my Utopian list includes:
WR Victor Cruz (RFA) NYG - Costing Dolphins 2014 1st round pick, Victor should restore respect on receiving corps.
TE Jared Cook (UFA) TEN - OK, I said Utopia. He will be unavailable one Titans places a franchise tag on him, in this Utopia, Titans GM forgets to tag him.
TE Dustin Keller (UFA) NYJ - Assuming Cook is unavailable, Keller could be a fine option to upgrade TE spot and extracting talent from division opponent.
TE Todd Heap (UFA) ARI - With Cook or Keller or without any of them, Heap is a great cheap option after his miserable year with Cardinals.
CB Marcus Trufant (UFA) SEA - A fill for Sean Smith.
Being rational, my guess is Dolphins will add:
WR Mike Wallace (UFA) PIT - Costing Dolphins something close to 60 milllions in 5 years.
TE Kevin Boss (UFA) KC - Questionable but somehow an upgrade.
WR Josh Cribbs (UFA) CLE - Adds skills to WR corps.
WR Steve Breaston (UFA) KC - Fine addition to WR corps.
CB Cedric Griffin (UFA) WAS - A fill for CB spot.
LT Sam Baker (UFA) ATL - Jake Long's replacement.
Then adding Chance Warmack will be acceptable because he should be BPA and a filler for Garner. I would be worried on how fitted is Warmack for zone-blocking.
