The Seahawks have had a defense-heavy draft in 2017 and this is a good thing
In the first eight picks of the 2017 NFL draft the Seahawks took three safeties. Seattle took only three offensive players in the first nine picks. This means the Seahawks are aware of what everyone else is as well: the Seahawks need youth on defense. The Seahawks championship window has been open for several years because of what the defense could do. Sure, Russell Wilson is fantastic, but offense does not win championships. Players like Richard Sherman, Michael Bennett and Earl Thomas do.
With that said, with their first pick (of two) in the seventh round, Seattle chose a wide receiver. David Moore of East Central University is the second receiver taken by Seattle in this draft. I am unsure what that says about how the Seahawks feel about the depth and health of their receivers. Sure, Paul Richardson is good but has not played a completely healthy season. Tyler Lockett has also been injured, but he has been productive.
Moore is 6’1″ and has run a 4.43 40. He is a bit of an unknown as he comes from a small school and did not play against great competition. Plus, he is a seventh round draft pick. Seattle has had much better success with undrafted players than they have had with seventh rounders. I am not sure Moore will make the active roster. More likely, Moore catches on with the practice squad and learns how the Seahawks want him to play the position. Otherwise he is a training camp cut and ends up on another team.
