Broncos hope Evan Mathis' arrival settles down young offensive line

Here’s a player-by-player look at the Denver Broncos' 53-man roster:

Quarterback (3)

Peyton Manning: Has averaged 4,954.3 yards passing and 43.7 TDs in three previous seasons with Broncos.

Brock Osweiler: Showed a comfort level in new offense, but Broncos will continue to push him to see if he can be The Guy someday.

Trevor Siemian: Rookie made it because he’s a legit prospect with big-time arm.

Running back (3)

C.J. Anderson: May have more carries by Week 10 than he’s had in his career to this point (186).

Ronnie Hillman: Showed in preseason, with 7.4 yards per carry, he’s a high-quality fit in zone-run game.

Juwan Thompson: Can play running back and fullback to go with full slate of special-teams work.

Fullback (1)

James Casey: Will see plenty of action at both fullback and tight end to go with plenty of special-teams duties.

Wide receiver (6)

Demaryius Thomas: Unquestioned Alpha receiver who has averaged 1,494.3 yards per season with Manning at quarterback.

Emmanuel Sanders: Coming off career year (101 catches, 1,404 yards), will play in slot and on outside.

Cody Latimer: Moves into the No. 3 spot, but Broncos want to see him take practice highlights into games.

Andre Caldwell: He was close to the roster bubble in camp, but the 30-year-old is reliable and has Manning’s trust.

Jordan Norwood: Would have made the roster in ’14 if not for ACL injury, and he's an option at punt returner if needed.

Bennie Fowler: Good size at 212 pounds, and Broncos see him as a prospect who can play outside and in the slot.

Tight end (3)

Owen Daniels: Will get plenty of targets in an offense he knows well, having played for coach Gary Kubiak in each of his nine previous seasons.

Virgil Green: Broncos will be in two-tight end sets often this season, and Green should get some looks in the passing game.

Mitchell Henry: Broncos see some potential in undrafted rookie who was waived by Green Bay Packers.

Tackle (3)

Ty Sambrailo: Rookie will start at left tackle. Has the athleticism, just has to make sure of his footwork and not get caught leaning.

Ryan Harris: Veteran may have given the Broncos more than they expected as he earned starting right tackle job.

Michael Schofield: Broncos believe he can be a future starter at right tackle, but still a question if has to play on left side.

Guard (4)

Louis Vasquez: Started the offseason as the only “given’’ in the offensive front.

Evan Mathis: Acquired as August drew to a close and was immediately inserted into lineup as starter at left guard.

Max Garcia: Rookie was moved out of lineup by Mathis, but a quality prospect who can play both center and guard.

Shelley Smith: Position versatility -- can play both guard spots and center in an injury situation -- earned him the spot.

Center (2)

Matt Paradis: In the youth movement up front, Paradis earned job with his smarts and feisty play.

James Ferentz: Houston Texans were hoping to bring him back on their practice squad, Broncos claimed him instead.

Nose tackle (2)

Sylvester Williams: Not the traditional two-gap nose tackle in a 3-4 look, but Broncos like his athleticism.

Darius Kilgo: Rookie earned his spot with a no-nonsense approach and flashed in the pass rush.

Defensive end (4)

Malik Jackson: Will flourish, in a contract year, no less, in Wade Phillips’ defense.

Vance Walker: Can play all three positions in the Broncos’ defensive front and did in the preseason.

Kenny Anunike: Had arthroscopic knee surgery late in training camp, but Broncos saw enough of a high-effort player to keep him.

Antonio Smith: A longtime favorite of defensive line coach Bill Kollar and Phillips.

Outside linebacker (5)

Von Miller: Poised to be in the Defensive Player of the Year conversation, in a contract year, if he stays healthy and plays with the effort he did in camp.

DeMarcus Ware: Broncos believe they can pump up his output, especially down the stretch, if they manage his snaps better.

Shane Ray: Rookie is going to play plenty and will be seen in some groupings with Ware and Miller also in the formation.

Shaquil Barrett: A guy who spent most of the 2014 season on the practice squad and won a job this time by consistently getting to the quarterback in preseason.

Lerentee McCray: Spent most of preseason on sideline with a groin injury, but Broncos kept him for depth.

Inside linebacker (4)

Danny Trevathan: After an injury-marred 2014, was back full speed by the time he closed out the preseason.

Brandon Marshall: Team’s leading tackler in ’14 will play this season with two screws in surgically repaired foot.

Todd Davis: A waiver claim last season, he has impressed as a quick study and a versatile backup.

Corey Nelson: A 2014 draft pick who showed plenty of special-teams chops to earn his spot.

Cornerback (6):

Chris Harris Jr.: A rare combination of elite on the outside and just might be the league’s best in the slot.

Aqib Talib: Was the unofficial interception leader in training camp practices.

Bradley Roby: Good enough to start for many teams and also good enough that the Broncos might play him at safety at times just to get him on the field more.

Kayvon Webster: Athletic corner who will play plenty in some of the specialty packages.

Lorenzo Doss: Rookie had the second-most interceptions of any defensive back on the draft board and was around the ball plenty in camp.

Curtis Marsh: Could lose his spot when T.J. Ward returns after one-game suspension, but Broncos liked Marsh’s work on special teams.

Safety (4)

Darian Stewart: Was signed in free agency to replace Rahim Moore and will play free safety in the base defense.

Omar Bolden: A returner who can play either safety spot as well as cornerback in some situations.

David Bruton Jr.: Bruton, who will start in place of Ward in the season opener, is longest-tenured homegrown Bronco as 2009 draft pick.

Josh Bush: Steadily climbed the depth chart in camp and reliable special-teams player.

Specialist (3)

Aaron Brewer (LS): Since making team as undrafted rookie in 2012, is one of the league’s most reliable at his position.

Brandon McManus (PK): Missed two field goal attempts in preseason -- both over 50 yards -- but needs to live up to potential Broncos think he has.

Britton Colquitt (P): Last season wasn’t his best, but he survived plenty of competition in the preseason to keep the job.
