Quarterback 

  • Ben Roethlisberger (back from injury - and another year older - so a decline is certainly possible - though he had one of his most productive seasons in 2018)
  • Mason Rudolph (played like an average backup in relief of Roethlisberger last year, he's not good enough to carry the team should Roethlisberger miss extended time again) 
  • Josh Dobbs (enters his fourth season with only 6 career completions, could not beat out Rudolph or Minshew in 2019) 

Running Back

  • James Conner (was somewhat disappointing across 10 2019 starts - averaged 4.0 ypc, but with Roethlisberger back - a return to 2018 Pro Bowl form is certainly possible... if he can stay healthy) 
  • Benny Snell Jr. (2019 third-rounder, failed to stand out as a rookie - below-average 3.9 ypc and did not contribute as a receiver, he will need to take a step forward in 2020 in order to fend off McFarland Jr.) 
  • Anthony McFarland Jr.* (rookie fourth-rounder from Maryland, two-year starter, had an explosive 2018 season - 1,034 rushing yards 7.9 ypc - but regressed in 2019 - 614 yards, 5.4 ypc - though a high ankle sprain likely played a role in the decline, he's undersized but runs with a fair amount of power, he also flashes explosive acceleration and speed on tape, he is relatively unproven in pass protection and as a receiver)
  • Jaylen Samuels (third-down back and special teamer, he's an inefficient runner - averaged only 2.7 ypc in 2019 but he is productive as a pass-catcher - caught 47 passes)

Wide Receiver

  • JuJu Smith-Schuster (numbers dropped significantly from his 2018 breakout - but like Conner - they should be on the rise again with Roethlisberger back at QB) 
  • Diontae Johnson (2019 third-rounder, impressed as a rookie - caught 59 passes for 680 yards and 5 TDs, he's got breakout appeal heading into the 2020 season) 
  • Chase Claypool* (rookie second-rounder from Notre Dame, broke out in 2019 with 66 catches for 1,037 yards and 13 TDs, he's got prototypical size/length and ran a 4.42 40, he also jumped 40.5 in the vertical, he excels in contested catch situations and frequently overwhelmed DBs with his superior physical traits, he is also an excellent run blocker, very high ceiling prospect) 
  • James Washington (production grew in year two - but still lacked consistency week to week, he did prove to be a capable vertical threat - as evidenced by his 16.7 yards per catch, he projects as the WR3 in 2020 - though he will have to hold off Claypool to keep the job) 
  • Ray Ray McLoud (kick return specialist) 


Tight End / Fullback

  • Vance McDonald (numbers dipped in 2019 - though the QB situation probably deserves most of the blame, with Roethlisberger back for 2020 expect production more in line with 2018 - 50 catches for 610 yards and 4 TDs) 
  • Eric Ebron* (in 2018 with Andrew Luck and the Colts he caught 66 passes for 750 yards and 13 TDs, his numbers went down in 2019 due to injury and poor QB play but he has the talent to put up big production with the Steelers) 
  • Zach Gentry (2019 5th rounder, caught 1 pass for 4 yards as a rookie, he's got intriguing size and could play an important role in the upcoming season if McDonald or Ebron suffer injures) 
  • Derek Watt* (starting FB and core special teamer) 

Offensive Tackle 

  • Alejandro Villanueva (reliable veteran LT, he consistently performs at a high level) 
  • Zach Banner (showed promise across 1 start and 14 game appearances in 2019, he's still relativity unproven but will start at RT in 2020) 
  • Chukwuma Okorafor (2018 third-rounder, was decent across four starts in 2019, he entered the league a few years ago as a smaller school development prospect) 

Interior Offensive Line

  • Maurkice Pouncey (solid center, 8 years of starting experience) 
  • David DeCastro (one of the league's most reliable right guards, has been the full-time starter in Pittsburgh since 2013) 
  • Matt Feiler (impressed across 16 starts at RT in 2019, but is expected to move to left guard in 2020) 
  • Stefen Wisniewski* (versatile interior lineman, has started 104 of  the 135 games he's appeared in, quality of play tends to be average but he brings great experience to the table) 
  • JC Hassenauer (went undrafted out of Alabama in 2018, spent time in the AAF before signing with Steelers, he's an unproven backup center) 
  • Kevin Doston* (rookie fourth-rounder out of UL-Lafayette, four-year starter, first-team AP All American in 2019, dominant tape, very powerful and strong, plays with excellent technique, drawback is limited athletic ability and movement skills, but still has starter upside) 


Defensive Line 

  • Cameron Heyward (superstar defensive lineman, first-team All-Pro in 2019, recorded 9 sacks and 11 TFL, excellent vs. the run) 
  • Stephon Tuitt (missed 10 games in 2019 with injury - recorded 3.5 sacks and 6 TFL before going down, has not completed a full 16 game season since his rookie year in 2014, when healthy he is a very disruptive player - strong vs the run and a pass rush threat) 
  • Tyson Alualu (run defense specialist, appeared in all 16 games last season - started 5, does not provide much pass-rush)
  • Isaiah Buggs (2019 fifth-rounder, did not see much game action as a rookie, he projects as a rotational lineman)
  • Chris Wormley* (acquired via trade with the Ravens, started 7/16 games in 2019, failed to stand out in Baltimore, but offers upside due to his excellent size and athletic testing numbers) 
  • Carlos Davis* (rookie seventh-rounder out of Nebraska, had a productive collegiate career, big/powerful player, but lacks quickness and movement skills, could find success at the pro-level in a nose tackle role) 

Outside Linebacker / Edge

  • TJ Watt (elite edge rusher, first-team All-Pro in 2019, recorded 14.5 sacks and 14 TFL) 
  • Bud Dupree (emerged as a force last season, recorded 11.5 sacks and 16 TFL, he's on the Pro Bowl watchlist heading into the 2020 season) 
  • Alex Highsmith* (rookie third-rounder out of Charlotte, ultra-productive in 2019 - 14 sacks and 21.5 TFL, he's a good athlete with lots of pass-rush moves - has a knack for getting around/behind blockers, but needs to get stronger - he won't be able to bully NFL OLs, has steal upside)  
  • Ola Adeniyi (has not seen much playing time since joining the team as a UDFA in 2018, but the coaching staff seems to believe he can add value)

Inside Linebacker 

  • Devin Bush Jr. (last year's first-round pick, started 15 games as a rookie and played well - flashed game-changing ability at times, he's a definite 2020 breakout candidate) 
  • Vince Williams (started 8 of the 14 games he appeared in last season, he's strong vs the run and a good downhill pass-rusher, but he struggles in coverage) 
  • Robert Spillane (core special teamer, expected to replace Tyler Matakevich) 
  • Ulysees Gilbert (2019 sixth-rounder, excelled on special teams before suffering a season-ending injury in Week 5, he's expected to be the top backup at ILB)

Cornerback

  • Joe Haden (entering his 11th season, he was a top-ten corner in 2019) 
  • Steven Nelson (one of the most underrated CBs in the league - he was consistently excellent last season and was deserving of Pro Bowl recognition) 
  • Mike Hilton (excellent nickel corner) 
  • Cameron Sutton (versatile DB - can play outside corner, nickel corner and safety, he seemed to have success regardless of where he lined up in 2019, could be the eventual replacement for Haden - who is entering a contract year) 
  • Justin Layne (2019 third-rounder, did not see much playing time as a rookie, but he was an excellent corner in college who tested out as an elite athlete at the 2019 Combine, a year two jump is certainly possible) 
  • James Pierre* (undrafted rookie free agent out of Florida Atlantic, played safety in 2019, solid college production, he's got great length but ran a slow 40 - 4.59, offers versatility in the secondary) 


Safety

  • Minkah Fitzpatrick (elite DB, the defense seemed to rapidly improve once he joined the team last season, a true playmaker on the backend) 
  • Terrell Edmunds (2018 first-rounder, was productive as a tackler last season but struggled considerably in coverage, he's entering a crucial season) 
  • Sean Davis* (signed with Washington in March - but didn't make the team and is now back with the Steelers, he only appeared in one game last season before going on IR with a shoulder injury, he was a solid/unspectacular starter in 2018, provides excellent depth and could push Edmunds for the starting job at some point) 
  • Jordan Dangerfield (core special teamer) 
  • Marcus Allen (2018 fifth-rounder, has spent most of his time on the practice squad, was a highly productive college player who could emerge in 2020, the team is reportedly cross-training him at linebacker) 

Special Teams 

  • Chris Boswell (highly accurate in 2019 - went 29 of 31 on FGs and 28 of 28 on XPs) 
  • Dustin Colquitt* (reliable veteran punter)
