Getting “Younger and stronger” on defensive line was one of Mike Tomlin’s stated objectives when the Steelers 2008 off season began. As it was, the Steelers would continue to open with the same starting threesome for the next 3 seasons, and it wasn’t until the beginning of the 2015 season that Steelers defensive line had been completely renewed.
The question heading into the 2017 NFL Draft is whether the Steelers want to stand pat or continue that renewal process.

Steelers Depth Chart @ Defensive Line Entering the 2017 NFL Draft – the Starters
Two studs in the form of defensive ends Cam Heyward and Stephon Tuitt bookend the Steelers defensive line.
During his first two years with the Steelers Cam Heyward doubters were easy to find, but in 2013 he beat out Ziggy Hood for the starting job and since then has established himself as one of the best defensive ends in the league. Cameron Heyward has 25 sacks, 18 passes defensed and a pair of forced fumbles and fumble recoveries to his name, but staistics do not do the man justice.
Week in and week out, Cameron Heyward makes the types of plays that don’t always show up on the stat sheet – unless you count the Steelers keeping more points on the board than their opponents.
Injuries to Brett Keisel thrust Stephon Tuitt into the starting line up late in the 2014 season, and no one has looked back since. With Cameron Heyward out for the second half of 2016, Stephon Tuitt stepped up as a leader of the unit, and despite Cam’s absence, the Steelers defense improved during the latter part of the season.
- The Steelers drafted Javon Hargrave in the third round of the 2016 NFL Draft.
If you’re surprised to discover that Javon Hargrave didn’t start the entire year, so was I. He had to wait until week to get his first start, but held on to the job from that point in the season, and established himself along side Artie Burns and Sean Davis as one of the three rookies who made an immediate impact to improve the Steelers defense.
Like his fellow rookies, something clicked for Hargrave during the second half of the season, as Hargrave got his first sack and first fumble recovery in the Steelers road win over the Cleveland Browns. Hargrave got another sack in the Steelers Thanksgiving win over the Colts, and also got to Tom Brady early in the AFC Championship game loss.
Steelers Depth Cart @ Defensive Line Entering the 2017 NFL Draft – Backups
Finding depth on the Steelers defensive line has been a challenge for Pittsburgh, forcing John Mitchell give his starters more snaps than he would like.
- In 2016 the Steelers defensive line took a step in the right direction, as L.T. Walton stepped up in Cam Heyward’s absence as did Ricardo Mathews.
The Steelers have taken another step in that direction by signing free agent Tyson Alualu, a former first round pick out of Jacksonville who can play either at defensive end or a nose tackle.
Tyson Alualu’s arrival might spell the end for backup nose tackle Daniel McCullers. The Shady Tree offers and imposing physical presence, standing at 6’7” 352 pounds and his snap count percentage did jump from 9.5% in 2015 to 17.4% in 2016, which is good, but given all of the injuries the Steelers suffered on the defensive line, you’d expect to see McCullers getting even more playing time.
Injuries forced practice squad player John Maxey into the action in late in 2016 and Maxley did his part to help prove Mike Tomlin’s “The Standard is the Standard.”
Steelers 2017 Draft Need at Defensive Line
The Steelers quest to rebuild their defensive line took longer than expected, although part of that is due to the longevity of Brett Keisel and Casey Hampton (although whiffing on Ziggy Hood didn’t help the cause.)
- Yet, even after the Steelers found three competent starters on defensive line, they struggled to back them up.
Time was that when the Steelers had to play without either Cameron Heyward or Stephon Tuitt, the Steelers run defense became a sieve and the team lost. That fact seemed to doom the Steelers chances after Cameron Heyward went on injured reserve in 2016.
However, the rest of the defensive line responded and not only survived but thrived despite Cam Heyward’s absence. That shows that the Pittsburgh Steelers have real depth on their defensive line, and the unit got deeper with the addition of Alualu Tyson.
Let’s be clear, in the contemporary NFL, the difference between an outside linebacker and a defensive end is getting blurred by the concept of “Edge Rusher” and that’s not even taking to account that the Steelers depend on their nickel package, which includes four down lineman, all the more frequently.
- “Edge Rusher” is clearly a Steelers priority, and if they find someone who falls into that category who happens to play defensive line, then the rating you’re about to read is rendered moot.
However, if we’re confining our conversation to conventional 3-4 defensive lineman then the Steelers depth chart is as solid as it has been during the Mike Tomlin era, and Steelers draft need at defensive line can be considered Low-Moderate.
