Pittsburgh had been in the market for additional help on the interior of its defensive line, and it's getting just that in Joseph-Day, a proven veteran that will further fortify a Steelers defense that has improved quite a bit since free agency has begun.

The Pennsylvania native spent each of the past two seasons as a member of the Tennessee Titans, recording 4.5 sacks and 85 tackles over 34 games (22 starts) during that stretch.

A sixth-round pick by the Los Angeles Rams in the 2018 NFL Draft out of Rutgers, Joseph-Day has 15.5 sacks and 314 tackles to his name in 105 career games.

If Joseph-Day is the final notable move the Steelers make on the open market, it would be a nice way to cap off an already productive offseason.

Steelers' Recent Additions

For as potentially impactful, and useful, Joseph-Day could be in Pittsburgh, he still doesn't rank near the top of the list in terms of the Steelers' newcomers.

In terms of money, wide receiver Michael Pittman Jr. is the costliest of the Steelers' additions thus far. After acquiring him and a 2026 seventh-round pick from the Indianapolis Colts in exchange for a 2026 sixth-rounder, Pittsburgh handed him a new three-year, $59 million extension that makes him the presumptive No. 2 option in the passing game behind DK Metcalf.

The Steelers' most notable splash on the free agent market was Jamel Dean, a long-time Tampa Bay Buccaneer who inked a three-year contract worth $36.75 milliion with the black and gold, making him the No. 2 cornerback next to Joey Porter Jr.

After watching Kenneth Gainwell, its reigning team MVP, head to the Tampa Bay Buccaneers on a two-year, $14 million deal, Pittsburgh rebounded by signing running back Rico Dowdle to a two-year, $12.25 million pact that will reunite him with Mike McCarthy, his former head coach with the Dallas Cowboys.

Elsewhere on the roster, the Steelers re-signed cornerback Asante Samuel Jr., linebacker Cole Holcomb, defensive lineman Esezi Otomewo and offensive lineman Jack Driscoll in addition to signing former first-round pick Darnell Savage at safety.
