Trade for Duane Brown further thins Seahawks' 2018 draft

Brown to have instant impact for Seattle offense (1:02)

Brian Billick breaks down LT Duane Brown's ability to become a difference-maker for the Seahawks in a short amount of time. (1:02)

The Seattle Seahawks' pending acquisition of left tackle Duane Brown from the Houston Texans marks the ninth trade the team has made since April, excluding pick-for-pick swaps on draft day. In addition to reshaping Seattle's roster, the net result of all that wheeling and dealing is the Seahawks have a lot less 2018 draft capital than they did a few months ago.

By my count -- and that of longtime Seahawks writer Chris Cluff -- Seattle has seven selections. That's standard, but that total is heavily concentrated in the back half of the draft and doesn't include picks in Rounds 2 or 3.

The Seahawks gave up their second-rounder for defensive tackle Sheldon Richardson and they're now giving up their third-rounder as part of a new agreement with Houston after cornerback Jeremy Lane's failed physical with the Texans.

OverTheCap.com doesn't project the Seahawks to receive any 2018 compensatory picks, which would have helped offset what Seattle has lost.

In eight drafts as Seattle's general manager, John Schneider has never made fewer than eight selections and has averaged more than 9.5. He has also traded down in the first round or out of it entirely in order to add more selections four times. It won't be the least bit surprising if he does it again to recoup some of what Seattle has given up in recent trades.

Here's a round-by-round accounting of Seattle's 2018 draft picks:

First round (1): The Seahawks have their original pick.

Second round (0): Traded to the New York Jets (DT Sheldon Richardson).

Third round (0): Traded to the Texans (LT Duane Brown).

Fourth round (1): Original pick.

Fifth round (3): Seattle traded a fifth to the Philadelphia Eagles (OT Matt Tobin) and acquired fifths in trades with the Oakland Raiders (RB Marshawn Lynch), New England Patriots (DE Cassius Marsh) and the Texans (Brown).

Sixth round (0): Traded to the Raiders (Lynch).

Seventh round (2): Seattle traded sevenths to Patriots (CB Justin Coleman) and Kansas City Chiefs (OT Isaiah Battle) and acquired sevenths from the Patriots (Marsh), Minnesota Vikings (CB Tramaine Brock) and Eagles (Tobin).
