The Pittsburgh Steelers did well to sign veteran DL Sebastian Joseph-Day, a steady, proven, and versatile run stuffer. I have no issues with the signing whatsoever. Adding Joseph-Day makes Pittsburgh five-deep along the defensive line. But the team will likely carry seven on the 53-man roster, and the unit needs one more type of player: a pass rusher.
No question, run defense comes first. That’s central to how the Steelers win. Can’t stop the run, never get the chance to rush the passer. Pittsburgh has fortified that group. There are four defensive linemen whose run defense is stronger than their pass rush: Cam Heyward, Derrick Harmon, Yahya Black, and Joseph-Day.
