According to ESPN's Mel Kiper, Jr., the Seattle Seahawks will have a shot at drafting the troubled but talented Robert Nkemdiche. Seattle could use a brand new pass rusher to help out the secondary, and Nkemdiche would be a perfect fit.
Seattle will see 4 defensive tackles - Jesse Williams, A.J. Francis, Ahtyba Rubin and Brandon Mebane - leave in free agency, which means there will be a deep need at defensive tackle. The Seahawks culture should do enough to help keep Nkemdiche on track, plus he will begin his career in one of the best places to win a title.
The Seahawks have a mixed bag of draft needs, and it is possible that they will have more needs after the free agency period, but they'll have several key free agents that could influence their draft needs. Seattle could see Jermaine Kearse and Ricardo Lockette walk away, which would create a need for a solid number-three wide receiver, but it may be able to find this later on in the draft with Braxton Miller, Will Fuller, or Michael Thomas.
The Seahawks may also be faced with life without linebacker Bruce Irvin, meaning they could take a look at some of the later round outside linebackers. Of the top prospects available at outside linebacker, two names stick out: Leonard Floyd and Joshua Perry. Both should be available by the time the Seahawks are ready to select their pick, and they must draft some young playmakers if this defense wants to remain elite.
