As of now there are only two legit 1st round OT's that fit the Seahawk profile, so no OT in the 1st round in this mock. I also don't have them drafting a DT in this mock, I think they will sign one of the many available DT's in free agency.
In this mock the Seahawks trade their 1st round pick to the Brown. Browns trade their 2nd round pick and 3rd round pick to the Seahawks to get back into the 1st round. With the Seahawks 1st round pick the Browns get their QB; either Texas Tech QB Pat Mahomes or Notre Dame QB DeShone Kizer.
2nd round pick (from the Browns) - (CB/S) Obi Melifonwu 6-4 219 lbs, Connecticut: If the Seahawks were to draft Obi I think it would be with the thought of moving him to CB. The Seahawks were one of the few teams that showed a lot of interest in Obi at the Senior Bowl. He looked comfortable lining up at CB in the Senior Bowl practice. In the video below Obi covers the slot WR and he looks comfortable in man coverage.
here is an interview he did at the Senior Bowl...
2nd round pick - (DE) Daeshon Hall 6-6 265 lbs, Texas A&M: Hall has great length and a good combination of size and speed. He may be a prospect that can add 10 pounds and occasionally kick inside to pass rushing DT.
3rd round pick (from Browns) - (RB) Kareem Hunt 5-11 215 lbs, Toledo: Hunt is not a speed guy, but IMO 40-yard times are overrated for RB's. Give me a RB with great balance, toughness/want to, and vision. Hunt is that guy!
3rd round - (SS) Marcus Maye 5-11 216 lbs, Florida: Maye doesn't have Chancellor's size, but Maye is not a lightweight at 216 lbs. Maye is a physical hitter, and looks to have good arm length for his size.
3rd round pick (comp for Irvin) - (OG) Isaac Asiata 6-3 325 lbs, Utah: The Seahawks interviewed Asiata during the Senior Bowl Week. Utah offensive line is known for being physical. Asiata received the Pac-12 best o-lineman award voted on by Pac-12 d-lineman. Asiata would give us more quilty depth on the o-line.
5th round pick (comp for Sweezy) - (WR) Ryan Switzer 5-9 185 lbs, North Carolina: Switzer is a quicker than fast WR. He is a instant open type of WR, he is ideal for quick hitting passes or teams with poor offensive lines that need WR get immediate separation.
6th round pick - (LB) Javancy Jones 6-1 245 lbs, Jackson St: Jones looks like a quick twitch athlete that has good size.
7th round pick - (TE) Antony Auclair 6-6 256 lbs, Laval: Auclair is another player the Seahawks interviewed. Auclair lookis like a beast as a blocker and more atheletic than Nick Vannett.
