(UPDATED 3/23) Per their usual MO, the Seahawks saw a lot more players leave than arrive in the first few days of the NFL year, but they have been making up ground.

Despite their seemingly overwhelming losses (eight top players), they have replenished their roster with cheap veterans, retaining four key players and adding six more.

The Hawks needed starter-level players at guard, running back and corner, plus a pass-rushing defensive tackle. They now have all but the corner.

Here’s what’s happening with each position:

QUARTERBACK
Roster: Russell Wilson, Trevone Boykin
Free agent: Austin Davis
What’s happening: Davis seems likely to return, especially because he is familiar with Brian Schottenheimer. The Hawks won’t pay much though.
Current position grade: A-

RUNNING BACK
Roster: Chris Carson, Mike Davis, J.D. McKissic, C.J. Prosise, Tre Madden (FB), Jalston Fowler (FB)
Free agents: Eddie Lacy, Thomas Rawls
What’s happening: After taking a couple of visits, Davis returned on a cheap one-year deal. Seattle had looked at veteran running backs Jonathan Stewart and DeMarco Murray but ended up going with the cheaper Davis. The Hawks seem quite likely to pick a runner in a loaded draft as well — and let Carson, Davis and the rookie battle for the starting job.
Current position grade: B-

WIDE RECEIVER
Roster: Doug Baldwin, Tyler Lockett, Amara Darboh, Jaron Brown, David Moore, Tanner McEvoy, Marcus Johnson, Cyril Grayson
Free agent: Paul Richardson (signed with Washington)
What’s happening: The Seahawks missed out on Jordy Nelson, who signed in Oakland, so added Brown, their speedy former division rival at Arizona. They brought Terrelle Pryor in for a visit, but he is expected to join the Jets. The Hawks are in decent shape here either way. Lockett should return to pre-injury form and excel in his contract year, and Darboh should step up in his second season. Moore and Johnson, acquired in the Michael Bennett trade, are wild cards. Some people are worried about this spot, but we’re not.
Current position grade: B+

TIGHT END
Roster: Ed Dickson, Nick Vannett, Tyrone Swoopes
Free agents: Jimmy Graham (signed with Green Bay), Luke Willson (signed with Detroit)
What’s happening: The Hawks are making big changes here, choosing Dickson over Austin Seferian-Jenkins (signed with Jacksonville) to replace Graham and Willson. They probably will add another tight end for cheaper than Dickson, whether a free agent or rookie. Brian Schottenheimer enjoys using two tight ends, so the Hawks will probably try to get at least five on the 90-man offseason roster.
Current position grade: C+

OFFENSIVE LINE
Roster: Duane Brown, Justin Britt, Ethan Pocic, Germain Ifedi, D.J. Fluker, Jordan Roos, George Fant, Rees Odhiambo, Isaiah Battle, Joey Hunt
Free agents: Luke Joeckel, Oday Aboushi, Matt Tobin (signed with New England)
What’s happening: The Hawks needed a veteran starting guard and brought in D.J. Fluker, who played for Mike Solari in New York last year. That presumably moves Pocic to left guard, with Ifedi staying at right tackle and hopefully benefiting from Solari and Fluker. The draft might bring competition as well.
Current position grade: C+

DEFENSIVE LINE
Roster: Frank Clark, Jarran Reed, Nazair Jones, Dion Jordan, Tom Johnson, Branden Jackson, Quinton Jefferson, Marcus Smith, Shamar Stephen, Noble Nwachukwu, Cliff Avril (injured), Malik McDowell (injured)
Free agents: Sheldon Richardson (signed with Minnesota)
What’s happening: Michael Bennett was traded to Philly and Richardson signed with the Vikings, cutting the starting line in half. But Jordan is expected to replace Bennett and the Hawks replaced Richardson with two former Vikings (Johnson and Stephen). Seattle reportedly expressed some interest in Ndamukong Suh but is not expected to be able to pay him. After bringing back Smith and the three J’s — Jordan (RFA), Jackson (ERFA) and Jefferson (ERFA) — and adding the ex-Vikes, the Hawks look pretty deep here. They still should be looking for the best pass rusher they can get (inside or out) in the draft.
Current position grade: B+

LINEBACKER
Roster: Bobby Wagner, K.J. Wright, Barkevious Mingo, D.J. Alexander
Free agents: Michael Wilhoite, Terence Garvin, Dewey McDonald
What’s happening: Mingo, the sixth pick in the 2013 draft, was brought in seemingly to fill Bruce Irvin’s old role, SAM/LEO. The Hawks likely will bring back McDonald and/or Garvin. Thanks to Wagner and Wright, this is the best unit on the team.
Current position grade: A

CORNERBACK
Roster: Shaquill Griffin, Justin Coleman, DeAndre Elliott, Neiko Thorpe, Mike Tyson, Akeem King, C.J. Smith
Free agent: Byron Maxwell
What’s happening: The Hawks cut their top three corners from 2016 — Richard Sherman, DeShawn Shead and Jeremy Lane — and will be going pretty young there this year. The sophomore Griffin is locked in at one starting spot, and the team is trying to re-sign Maxwell to step in for Sherman full time. That effort might be failing though; the team traded for Smith and also brought in former 49ers starter Dontae Johnson for a visit. Coleman was a great RFA tender as the nickel back, and Elliott and special-teams ace Thorpe are decent backups.
Current position grade: C+

SAFETY
Roster: Earl Thomas, Bradley McDougald, Delano Hill, Tedric Thompson, Maurice Alexander, Alex Carter, Kam Chancellor (injured)
Free agents: None
What’s happening: McDougald was probably Seattle’s most important free agent, based on value and need. With Chancellor not expected to play again, McDougald would remain the strong safety. But, if Thomas is traded as well, McDougald likely would move to free safety and Hill would step up at strong. If Thomas is dealt for a first-round pick, it could put Seattle in position to draft Derwin James, with whom Thomas has been training. The team also just added Alexander, who started 23 games for the Rams the past three years; he could be a diamond in the rough. Until we know Thomas’ fate (traded or extended), this position is going to be in flux.
Current position grade: B+

SPECIAL TEAMS
Roster: P Jon Ryan, K Jason Myers, LS Tyler Ott
Free agent: Blair Walsh
What’s happening: Myers was added in January and the Seahawks are still on the lookout for competition. They brought in Caleb Sturgis, but he signed with the Chargers. Seattle will add another kicker before camp, whether it’s some drifting vet or a rookie.
Current position grade: C
