Well, obviously so much depends on free agency. Ideally, Miami would land an upgrade at guard during the free agent period. To me that would really open up the draft to concentrate mostly on defense. That's the strength of the draft.
That said, my biggest draft crush is probably Warren (yes a tight end) because I can visualize what he'd mean to the Dolphins offense. But, I'd be happy with any of the following that are also high on my list.
Graham DT - just a monster. I think he'll be gone.
Nolen DT - I think he may end up being the best pass rusher inside.
Pearce DE -- I think he may end up being the best outside pass rusher.
Starks S -- from a positional value concept, no. But he's so versatile that maybe??
Walker LB -- Talk about versatility.
Ersery OT/OG --- He's often mocked to SF as a scheme fit there. Which means he likely fits with Miami. Can play tackle or guard.
Any of the three larger DE's -- Landon Jackson (love him, though he has had injuries), Nic Scourton, Shemar Stewart)
