North Dakota State OT Billy Turner (above) could move to guard for the Dolphins.
Billy Turner, OG (Round 3, pick No. 67)
The Dolphins started addressing their four holes offensive line in free agency, and by the third round of the NFL draft, they had filled their final void. Billy Turner is a raw prospect and didn't face much top-notch competition at North Dakota State, but he has the tools to develop into a stout interior offensive lineman and the foot quickness to give the Dolphins the missing element of a pulling guard on the inside.
Walt Aikens, CB (Round 4, pick No. 125)
With Jamar Taylor and Cortland Finnegan seemingly in a competition for the outside and slot duties, the Dolphins decided to add to the competition at cornerback.
Walt Aikens ran the 40-yard dash in 4.49 seconds at 6'1" and 203 pounds, making him a great height-weight speed prospect to develop. He will need to work on his technique and did not face top-notch competition in his career at Liberty, but he may get an opportunity to develop on the sideline.
Arthur Lynch, TE (Round 5, pick No. 155)
With Charles Clay on the roster, the Dolphins weren't in dire need of a tight end, but Clay is not seen as a talented blocker. At 6'5" and 258 pounds, Lynch has upside in that role, but he is not yet ready to contribute in that sense.
If he adds some strength and works on getting a good base under him as a blocker, he could step in as an in-line blocker. For now, he will add another big-bodied presence over the middle and in the red zone.
Jordan Tripp, LB (Round 5, pick No. 171)
The Dolphins signed two big-name linebackers last offseason in Dannell Ellerbe and Phillip Wheeler, but their depth at the position is shaky. Jordan Tripp has the ability to play either inside or outside, but he is at his best when he can shoot gaps in the line and chase down plays on the outside. His special teams experience will help him contribute even if he doesn't see the field as a rookie.
