The Seahawks have been awarded four compensatory picks for the 2015 NFL Draft. They fall at the end of the fourth round (134 overall), the fifth round (170), and at the end of the sixth round (209, 214).
As I wrote this morning, teams can receive a maximum of four comp picks. Seattle was expected to receive the maximum of four picks, and these picks result from the Seahawks losing four "big" to "mid-level" free agents on the open market last year while they concentrated on re-signing their own guys to extensions. Gone were Golden Tate ($6.2M APY in Detroit), Brandon Browner ($5.05M APY in New England), Breno Giacomini ($4.5M APY in New York), and Clinton McDonald ($3M APY in Tampa Bay), and after those guys, the Hawks also lost Walter Thurmond, Paul McQuistan, and Chris Maragos, but again, you can only get four comp picks.
Because Seattle made no big-time outside signings (Kevin Williams was post-June-1st, as was Eric Winston, and Terrelle Pryor was acquired in a trade), all four counted into the NFL's convoluted and secretive formula.
Seattle's draft now looks like this, going in:
2nd Round: (native)
3rd Round: (native)
4th Round: (from New Orleans for Max Unger)
4th Round: (native):
4th Round: (comp)
5th Round: (native):
5th Round: (comp):
6th Round: (from New York for Percy Harvin)
6th Round: (comp)
6th Round: (comp)
7th Round: (native)
The Hawks lost their native Sixth Round pick in trading for Marcus Burley last year but gained New York's by trading Percy Harvin. They added New Orleans' Fourth Round pick after trading away their First and Max Unger to the Saints.
