We know that Seattle breaks down their draft into "pockets." Last year for example, they had pass rush very early, RB in round 1-3 (then forced to go 4th round), QB 4-6 (forced to go 3rd round), etc.
I suspect Seattle's "zone" table probably looks like this:
Pass rush: 1st round, rounds 3-5. I think Seattle will draft at least 2 pass rushers, one very early and a second in the middle rounds. If Richardson or Short are there, I'd be stunned if Seattle passed.
Red Bryant backup: rounds 3-7. A big 5-tech. Optional pick, but could happen if they really like a guy.
Wide receiver: rounds 2-4. Seattle might draft a second WR even later. I could see Seattle going WR in round one if they don't like the pass rush options there.
Tight end: rounds 2-6. Chris Gragg in round 5 or round 6 sounds about right.
Quarterback: rounds 4-7. UDFA a possibility.
Offensive tackle: rounds 3-7.
Corner: rounds 6-7.
Safety: rounds 6-7, barring someone like Vaccaro reaching #25.
Linebacker: rounds 2-5.
An example of what that draft might look like:
1st: DT
2nd: WR
3rd: DE
4th: LB
5th: T
5th: TE
6th: QB
7th: CB
7th: S
7th: WR #2 or DE #2 or 5-tech
