I don't think the Seahawks releasing Scruggs had anything to do with his talent or lack of.
Not every single roster move has to be dissected with a player getting ripped apart to be analyzed against weighted expectations.
It could just be a numbers game and the Seahawks needed bodies in their secondary.
And the reason why he isn't getting PT is because he had a setback with his knee I believe after the last PS game, then Williams and Hill kind of settled into effective roles in the rotation and Scruggs became the odd man out. It happens, especially when you have to carry 7 WRs and keep 5-6 active when most teams roll with 4. It happens when teams are forced to sit 7 players every week regardless if they are healthy or not.
Frankly, though I would like to see them get Scruggs some PT. I would deactivate Marsh for now because I think they have way too many pass-rushers that they are trying to get snaps. And especially since Irvin has been working his way back into the mix this year as one of the better pass-rushers on the team this far.
I just would like to see Quinn, bring back the Bryant D-Line with the starters being:
Bennett - Williams - Mebane - McDaniel
Hill and Scruggs rotating with the Big Bads to keep them fresh.
With Avril and Schofield taking over for Bennett every so often to keep all the pass-rushers fresh.
Then in the Nickel you'd bring in;
Irvin/Schofield, Bennett, Hill/Williams, Avril
The Base D-Line wears out the O-Line down, and the Nickel D-Line reaps the benefit.
