It's too soon for roster predictions. This is a snapshot of the Seahawks player personnel as of today, with my best guesses on depth. Corrections and opinions encouraged.

For this purpose, Bubble is a wide conceptual space between Lock (~100% to make the team) and Longshot (long odds of making it).

Updated to reflect roster moves on 4/28.

Quarterback
Last season: 3
Currently: 3
Lock: Matt Hasselbeck, Charlie Whitehurst
Clipboard: Mike Teel
Camp body: -

Presumably someone will be brought in to take snaps in camp...right? That they haven't yet may indicate that Carroll doesn't want Whitehurst looking over his shoulder. 

Running Back
Last season: 5
Currently: 8
Lock: LenDale White, Leon Washington, Owen Schmitt
Bubble: Justin Forsett, Julius Jones
Longshot: Quinton Ganther, Louis Rankin, Ryan Powdrell

Writing is on the wall for Jones. Loving LenDale as a Hawk and really hope Washington can come back strong from an ugly injury. Justin Griffith is listed on the Seahawks roster but remains unsigned, so far as I can determine. Powdrell is the only other fullback on the roster. LenDale looks like a fullback, maybe we could roll with three backs and Schmitt?

Wide Receiver
Last season: 5
Currently: 14
Lock: T.J. Houshmandzadeh, Golden Tate
One or the other: Deon Butler, Deion Branch
Bubble: Sean Morey, Ben Obomanu, Ruvell Martin, Jameson Konz, Mike Williams, Reggie Williams
Longshot: Mike Hass, Patrick Carter, Michael Jones, Quintin Hancock

Got to figure they keep six, because look at all those guys. Butler and Branch can't both make the roster. Morey might be close to a lock. I like Mike ahead of Reggie, and Konz ahead of both. Competition! 

Tight End
Last season: 3
Currently: 6
Lock: John Carlson, Chris Baker
Bubble: Anthony McCoy, Cameron Morrah 
Longshot: Patrick Devenney, Jason Pociask

We're slightly loaded at this position! No pot jokes, they offend Carlson.

Offensive Line
Last season: 9
Currently: 15
Lock: Russell Okung, Ben Hamilton, Chris Spencer, Max Unger, Sean Locklear, Ray Willis
Bubble: Steve Vallos, Mansfield Wrotto, Mike Gibson
Longshot: Jeff Byers, Mitch Erickson, Kyle Burkhart, Adrian Martinez, Jacob Phillips
Retiring: Walter Jones

Look at that. We really got Okung. Hello, decent O-line.

Defensive Line
Last season: 11
Currently: 14
Lock: Lawrence Jackson, Colin Cole, Brandon Mebane 
Bubble: Red Bryant, Chris Clemons, Kevin Vickerson, E.J. Wilson, Nick Reed, Craig Terrill, Dexter Davis, Robert Henderson
Longshot: Ricky Foley, DeMarcus Granger, Rob Rose

3-4, stand-up end, who the hell knows.

Linebackers
Last season: 6
Currently: 9
Lock: Aaron Curry, Lofa Tatupu, David Hawthorne, Will Herring
Bubble: Leroy Hill, Matt McCoy
Longshot: Anthony Heygood, Kevin Dixon, Joe Pawelek

Much depends on whether Hill gets a long suspension or worse.

Cornerbacks
Last season: 4
Currently: 8
Lock: Marcus Trufant, Josh Wilson
Bubble: Kelly Jennings, Walter Thurmond III
Longshot: Roy Lewis, Marcus Brown, Josh Pinkard, Kennard Cox

Here's to your health, Mr. Thurmond.

Safeties
Last season: 4
Currently: 7
Lock: Earl Thomas, Jordan Babineaux
Bubble: Kam Chancellor, Jamar Adams
Longshot: Will Harris, James Brindley, Quinton Teal

It is assumed Lawyer Milloy will re-sign to compete for a backup spot.

Specialists
Last season: 3
Currently: 4  
Lock: Olindo Mare*, Jon Ryan
Bubble: LS Patrick MacDonald, LS Matt Overton

Bu-bye, Malone! We hardly knew ye.
