The Pittsburgh Steelers won the AFC North in 2020 but the season didn't end remotely like the team had planned. This offseason, the Steelers have spent a significant amount of time and money fixing the issues on both offense and defense.Now that training camp and preseason games have concluded, the Pittsburgh Steelers have trimmed down their roster and created a depth chart for Week 1 of the regular season. The Steelers, as with most teams, could still make additional roster additions before the start of the season.The Steelers will get their first test right out of the gate with a trip to Orchard Park, New York, to take on the Buffalo Bills.Pittsburgh Steelers 53-man rosterPittsburgh Steelers offenseQuarterback Ben Roethlisberger may be entering his final season in the NFL, but the Steelers don't appear to have a succession plan. After ranking near the bottom in the running game, the Steelers drafted Alabama running back Najee Harris, who will now be Pittsburgh's lead back. The offensive line has been a battle all training camp and is finally set. As things stand, weapons are running a little low in Pittsburgh.Quarterback: Ben Roethlisberger, Mason Rudolph, Dwayne HaskinsRunning Back: Najee Harris, Benny Snell Jr., Anthony McFarland, Kalen BallageWide Receiver: JuJu Smith-Schuster, Chase Claypool, Diontae Johnson, James Washington, Ray-Ray McCloudTight End: Eric Ebron, Pat Freiermuth, Zach GentryFullback: Derek WattCenter: J.C.

Watt had a career season in 2020 and many believe he was snubbed for Defensive Player of the Year honors. After losing Bud Dupree in free agency, the Steelers signed veteran outside linebacker Melvin Ingram and recently traded for linebacker Joe Schobert from the Jaguars.Defensive Tackle: Cameron Heyward, Henry Mondeaux, Isaiah LoudermilkNose Tackle: Tyson Alualu, Isaiah Buggs, Carlos DavisDefensive End: Stephon Tuitt, Chris WormleyOutside Linebacker: T.J.

Cam Sutton will likely be the primary slot guy, but would guess the Steelers are aggressive in trying to add another corner to the room.— Brooke Pryor (@bepryor) August 31, 2021Pittsburgh Steelers special teamsThe Pittsburgh Steelers' special teams will have a bit of a new look in 2021. The Steelers parted ways with punter Jordan Berry and long snapper Kam Canaday but have retained kicker Chris Boswell. Rookie punter Pressley Harvin III and free-agent long snapper Christian Kuntz won the preseason competition.The Steelers have indeed moved on from P Jordan Berry, source confirms. Rookie seventh-round pick Pressley Harvin III wins the job out of camp.
