The Pittsburgh Steelers open training camp July 28 at St. Vincent College in Latrobe, Pennsylvania. Here's a starting lineup projection:
Quarterback (Ben Roethlisberger): A 12-year veteran, he holds a 113-56 career record and enters the season five yards short of 43,000 passing yards.
Running back (Le'Veon Bell): Bell, one of the game's best all-around tailbacks, was averaging nearly 100 rushing yards per game before suffering a knee injury in Week 8.
Fullback (Roosevelt Nix): The Steelers still use a traditional fullback, and Nix is the only fullback on the current roster. He's safe.
Receiver (Antonio Brown): After setting an NFL record with 264 catches over a two-year span, Brown looks to maintain his place as the game's top receiver.
Tight end (Ladarius Green): The Steelers signed Green to a four-year, $20 million contract this offseason to become a new vertical threat up the middle of the field.
Left guard (Ramon Foster): After consistent play spanning 87 starts, Foster earned a three-year contract worth $9.6 million this offseason.
Right guard (David DeCastro): DeCastro's All-Pro performance in 2015 is expected to earn him a hefty contract extension this offseason.
Right tackle (Marcus Gilbert): He has become an anchor on the line after flourishing at right tackle and getting in ideal shape.
Center (Maurkice Pouncey): Pouncey, a former Pro Bowl selection, hopes to regain his role as the offense's emotional leader after missing 31 games in the last three seasons.
Defensive end (Cam Heyward): He was probably the Steelers' most consistent performer on defense last season, finishing with 54 tackles and seven sacks.
Defensive end (Stephon Tuitt): Tuitt solidified a starting role with 6.5 sacks in 14 games, pairing with Heyward to form a formidable defensive front.
Nose tackle (Dan McCullers): He has made minimal impact in two seasons but has obvious strength at the line of scrimmage that intrigues coaches.
Outside linebacker (Bud Dupree): He hit a rookie wall with zero sacks in his final eight games, but has flashed enough ability to enter the season as the favorite to start.
Outside linebacker (Jarvis Jones): A former first-round pick, Jones enters a make-or-break season after the Steelers declined his fifth-year option.
Inside linebacker (Ryan Shazier): Shazier expects to make a sizable jump in his third season after 87 tackles and 3.5 sacks last year while showcasing elite athleticism.
Inside linebacker (Lawrence Timmons): The longest-tenured Steelers defender has started 110 games and recorded 867 tackles in nine seasons.
Cornerback (William Gay): Despite upgrades in the secondary in the past two drafts, Gay remains the team's key veteran at cornerback and signed a three-year deal to remain with the team.
Safety (Mike Mitchell): Coach Mike Tomlin has trust in Mitchell, who adds splash plays to the defense. He had three interceptions and two forced fumbles last year.
Kicker (Chris Boswell): Boswell made 26 of 29 field goals (89.6 percent) in his first full NFL season, easing concerns about the team losing veteran Shaun Suisham to a knee injury.
Punter (Jordan Berry): He averaged 42.6 yards per punt on 59 attempts as a rookie.
Long snapper (Greg Warren): Warren hasn't missed a regular season game since 2009 and re-signed with the Steelers in the offseason.
