Here's a player-by-player look at the Seattle Seahawks' 53-man roster:
Russell Wilson: His preseason performance was shaky, but Wilson has 46 touchdowns and 16 interceptions the past two seasons to lean on. With Jimmy Graham in the mix, this could be his best season yet.
Tarvaris Jackson: The veteran has battled an ankle injury during the preseason, but Pete Carroll said he'll be good to go for the opener against the Rams.
RUNNING BACK (5)
Marshawn Lynch: He has had 280 carries or more in four straight seasons, and Lynch is a good bet to hit that mark once again in 2015. The Seahawks are counting on him to make up for the lack of continuity on the offensive line, especially early in the season.
Fred Jackson: Look for the 34-year-old to spell Lynch, especially on third downs during which he's dependable as a receiver and pass protector.
Derrick Coleman: A foot injury sidelined him for most of last season, but Coleman will get another shot to be the Seahawks' starting fullback.
Will Tukuafu: In an era in which teams are fazing out fullbacks, the Seahawks kept two with Tukuafu and Coleman.
WIDE RECEIVER (6)
Doug Baldwin: He's coming off a year in which he set career highs with 66 catches and 825 yards. The most consistent producer out of this group, Baldwin will start and rarely come off the field.
Jermaine Kearse: He'll begin the season opposite Baldwin and figures to see plenty of one-on-one matchups.
Tyler Lockett: The rookie was electrifying during the preseason, scoring three touchdowns of 60-plus yards on a kickoff return, a punt return and a reception. Lockett has given the coaches no choice but to carve out a role for him on offense.
Chris Matthews: Due in part to a shoulder injury, Matthews had a quiet preseason. But that performance in the Super Bowl is impossible to forget, and he could be the biggest wild card on this offense.
Ricardo Lockette: He might not play a lot on offense, but is a core special teams player and will likely be active on game days.
B.J. Daniels: Coaches love to preach the "more you can do" mantra, and Daniels is proof that that's not all talk. He earned a spot by showing the ability to play quarterback, wide receiver and returner on special teams.
TIGHT END (3)
Jimmy Graham: He'll be the focal point of the passing game and is the favorite to lead the team in receptions, yards and touchdowns.
Luke Willson: Don't be surprised if the Seahawks increase their use of two-tight-end sets with Willson and Graham on the field together.
Cooper Helfet: Barring an injury to one of the two guys above, he's unlikely to see the field much on offense.
OFFENSIVE LINE (9)
Russell Okung: He's the surest thing they've got on the offensive line and will start at left tackle for the sixth straight season. Okung is scheduled to become a free agent after 2015.
Justin Britt: The second-year player made the switch from right tackle to left guard during the preseason and had some issues. It's reasonable to expect that he'll be more comfortable in December than he is in September.
Drew Nowak: The center spot was up for grabs, and Nowak won out. He'll have his hands full in his first career start against the Rams' talented defensive line.
J.R. Sweezy: He and Okung are the most experienced starters on the offensive line. Look for the Seahawks to run behind Sweezy at right guard plenty this season.
Garry Gilliam: Like Nowak, he'll be starting for the first time in his career, manning the right tackle spot.
Alvin Bailey: He couldn't hold on to a starting job, but chances are Bailey will have to play significant snaps at some point as the Seahawks' swing tackle/guard.
Patrick Lewis: He'll likely be active on game days as the backup center.
Mark Glowinski: He may not see much game action, but the organization drafted Glowinski in the fourth round and will develop him.
Kristjan Sokoli: A sixth-round pick in this year's draft, he showed some positional versatility and beat out fourth-round pick Terry Poole for a spot on the roster.
DEFENSIVE LINE (9)
Cliff Avril: The veteran has had 13 sacks in two seasons with the Seahawks and will start at one defensive end spot.
Michael Bennett: He was unhappy with his contract but decided to show up. Bennett has 15.5 sacks the past two seasons. He'll start on the edge and move inside in sub packages.
Ahtyba Rubin: A free-agent signee from Cleveland, Rubin's job is simple: get his hands dirty and stop the run on early downs.
Brandon Mebane: After missing the second half of last season with an injury, Mebane was giving offensive linemen fits toward the end of the preseason.
Frank Clark: Expectations are high for the rookie, who looked flat-out unblockable at times during the preseason. He'll see significant snaps in a rotational role.
Jordan Hill: The third-year player is an important part of the defensive line rotation.
Cassius Marsh: He'll make his mark on special teams and rotate in at the edge spots.
Demarcus Dobbs: The fifth-year veteran will serve a backup/rotational role on the interior.
David King: He may not see a lot of snaps on defense, but King played his way onto the roster with a strong summer.
Bobby Wagner: One of the best in the league in his position, Wagner has a new contract in hand going into the season.
K.J. Wright: He gets less recognition than some of the other members of the defense, but is an important cog in what could once again be the league's best unit.
Bruce Irvin: He'll bounce back and forth between linebacker and defensive end. Entering the last year of his contract, Irvin is coming off a 6.5-sack season.
Kevin Pierre-Louis: A fourth-round pick in 2014, Pierre-Louis had a strong preseason and looked like he could be starter material down the road.
Brock Coyle: He too looked good during the preseason and will be a core special-teams player.
Mike Morgan: Carroll said he's got a "legitimate" hamstring injury, so Morgan will likely be inactive to start the season.
Richard Sherman: Nothing to see here. The expectation is that Sherman will play at an All-Pro level for the fourth straight season.
Tharold Simon: If Williams struggles, he'll get a chance to start. Otherwise he'll serve as the top backup on the outside.
Tye Smith: A fifth-round pick, the rookie flashed plenty in the preseason and could compete for the nickel job.
Earl Thomas: Carroll does not sound concerned about Thomas playing at a high level despite missing all of the preseason with a shoulder injury.
DeShawn Shead: One of the Seahawks' core special teams players, he's also an option to fill in for Chancellor.
Kelcie McCray: Acquired from the Chiefs for a fifth-round pick, McCray could see more than just a special-teams role in Seattle.
Steven Terrell: He'll be Thomas' primary backup at the free safety spot and a special-teams contributor.
Clint Gresham: He enters his sixth season as the team's long-snapper.
Jon Ryan: The 33-year-old will be the Seahawks' punter for the eighth straight season.
Steven Hauschka: His 60-yard game-winner against the Chargers in the third preseason game provided a nice tuneup for the real thing.
