Seahawks Malik McDowell remains out; Shaquill Griffin looks like mainstay

Here's a look at the first-half impact of the Seattle Seahawks' draft class:

Malik McDowell, DL, second round: The Seahawks made McDowell their top pick with the hope he could make an immediate impact as an interior pass-rusher. That will have to wait. McDowell has been sidelined since he suffered what the team has described as a serious concussion during a summer ATV accident. It seems more likely than not he'll miss his entire rookie season. Grade: Incomplete.

Ethan Pocic, OL, second round: He beat out Mark Glowinski to be Seattle's starter at left guard while Luke Joeckel recovers from knee surgery. He had played only special teams before that, which was somewhat surprising given he can be used in multiple positions and Seattle's offensive line had two openings. Pocic was a jack-of-all-trades in college. The Seahawks need him to master left guard for now. Grade: Average.

Shaquill Griffin, CB, third round: Other than Richard Sherman, no rookie cornerback under coach Pete Carroll has made as significant an impact as Griffin. He began the season as Seattle's No. 3 corner but has since overtaken Jeremy Lane as the starter opposite Sherman. Seattle has cycled through players at that spot since Brandon Browner left after the 2013 season. Griffin is there to stay. Grade: Above average.

Delano Hill, S, third round: He's been a regular on special teams but hasn't made his way onto the field on defense. And he wasn't expected to with Bradley McDougald ahead of him as Seattle's third safety behind Earl Thomas and Kam Chancellor. Grade: Incomplete

Nazair Jones, DT, third round: Jones had one of the more incredible NFL debuts imaginable when he intercepted an Aaron Rodgers pass and returned it 24 yards for a touchdown that was negated by a block in the back -- on his first career snap. He's been a regular in Seattle's defensive line rotation and has provided some of what the Seahawks hoped McDowell would give them. Grade: Above average.

Amara Darboh, WR, third round: Darboh's best moment was when he drew a 20-yard pass-interference penalty that helped set up the winning touchdown against the San Francisco 49ers in Week 2. Aside from that, he hasn't made much of an impact while serving as Seattle's fifth receiver. Grade: Incomplete.

Tedric Thompson, S, fourth round: He's been inactive for all but one game and didn't play then. With McDougald and Hill as the backup safeties ahead of him, Thompson may not see the field as a rookie. Grade: Incomplete.

Mike Tyson, CB, sixth round: Tyson played safety and nickelback in college, but the Seahawks are trying to convert him to the type of big-bodied cornerback they like. He's on the practice squad. Grade: Incomplete.

Justin Senior, OT, sixth round: Senior began training camp on the physically unable to perform list because of a knee injury and reverted to Seattle's roster after he was waived/injured and went unclaimed. Grade: Bring on 2018.

David Moore, WR, seventh round: Moore couldn't claim the final spot in Seattle's receiver corps and ended up on the practice squad. His combination of size (6-2, 219) and speed (4.43) make him an intriguing prospect. Grade: Incomplete.

Chris Carson, RB, seventh round: What might Seattle's running game look like if Carson were still leading it? He beat out Eddie Lacy and Thomas Rawls to be the team's lead running back, but he went down in Week 4 with an ankle injury that required surgery. Rawls' inability to regain his 2015 form is a reminder that nothing can be assumed with running backs coming off serious leg injuries. But if Carson makes a full recovery, he'll be the favorite to be Seattle's starter next season. Grade: Above average.
