Powell has tremendous size for his position, listed at 6-foot-3, 209 pounds and comes from a powerhouse school like OSU. Let's face it, the Miami Dolphins can't count on Louis Delmas to stay healthy for an entire season. Delmas could groom Powell and show him the ropes as his eventual replacement along side Reshad Jones.
Missed all of 2015 with a foot injury, but was a beast for the Razorbacks leading up to his senior year, becoming a emifinalist for the Earl Campbell award given to the nation's top college RB. Williams could be the thunder to Lamar Miller.
The Dolphins have a couple of solid line backers in Koa Misi and Jelani Jenkins, but they lack one that is good in coverage. Deion Jones is a good line backer that can cover as well as get to the quarterback.
At this stage, Bush is likely to be the best secondary player available and will serve as a future counterpart to Reshad Jones, a former late round pick.
