I am thinking front 7 defender or OT at #18, that should be a confluence of team need and value.
#36 could be one of the top 3 RB's or Center. There should be value at S but I am not sure Miami is looking there that early. Another pass catcher would not be out of the question, especially
if they land Pitts.Not to mention Edge/LB or OT if they don't go that way earlier.
Imo Sewell, Slater (both likely off the board), Darrisaw, and Jenkins are the OT's worth considering, and Parsons is the Front-7 player worth considering at 18. The risk/reward for the Edge prospects isn't there. Lot of intriguing guys but no one I'd feel good about paying off that kind of investment. At 36, if a guy takes a bit to develop and is never more than pretty good, you'd like more, but it's fine. At 18, I want a better floor-ceiling combo.
