Half-assed internet speculation, sprinkled with some light reading at SDB. There are some good players on his list, but of all those players only Lockette truly feels 'Seahawky' to me.
Perriman is really good but he kind of goes against the recent drafting history of the team. Usually when it comes to WRs Seattle targets prototypical guys, with the exception of Golden Tate back in 2010. Perriman is a bit of an oddball, almost looks like a RB playing WR. Then again, Seattle does tend to draft "odd" players quite often in the later rounds, they just don't do it as often early. I think he'll be gone by #63 either way. Dude is a PLAYMAKER. Would be a great pick if it happened, I'm just not seeing it in my crystal ball for whatever reason.
It's hard to get a bead on Cable's OL preferences. If anything, he has a history of getting the Seahawks to draft players a round or two early (Moffitt, Britt, Carp, etc). I thought Bitonio fit him reasonably well, and the Hawks passed on Bitonio at #32 last year to select Britt a round later. Britt still has a chance to be okay, but that's a goof up.
I don't know if they draft him, but Devin Smith to Seattle feels so obvious to me, though it would require them to move up. Seattle needs an elite deep threat and they need an ace KR. Smith also plays with a chip on his shoulder and came from a very similar offense to Seattle's at Ohio State. He's the perfect WR for Seattle and their current needs. I suspect that Smith is their plan A and Lockette is their plan B. I'd be very curious to know what they think of Perriman, whether they think he's the piece they need or if he's too redundant with guys on the roster already.
I still think Ajayi is the RB Seattle is looking at the longest. I could easily see them penciling him in at #95. He's got some extremely rare traits that Seattle is always on the lookout for. I'm not saying he's a perfect RB, but he's talented in some key areas and he just "feels" uber Seahawky, and PC/JS tend to draft by feel.
Regarding the South Carolina RB, I don't think he's actually all that talented, even if he does fit our MO. Seattle can easily go through this draft without selecting a RB at all, I think if they do take one it will be a guy with rare qualities. If they do take Davis, it will be only if he falls very far in the draft and it becomes a Spencer Ware type of situation for them. And that's assuming they have a much higher opinion of him than I do.
