The Pittsburgh Steelers haven't been making quite as many headlines this free agency period as they did last year, but that isn't necessarily a bad thing. It would be hard to top the massive trades for DK Metcalf and Jalen Ramsey anyway, but they have been praised by many this offseason for making smart, calculated moves.
The trade for Michael Pittman Jr. (essentially a salary dump), the reasonably cheap deal for veteran corner Jamel Dean, and the boost to the running back room with Rico Dowdle have given the roster a much-needed infusion of veteran, but not ancient, talent.
Their latest move continued that mantra, bringing in former Tennessee Titans defensive lineman Sebastian Joseph-Day on a two-year, $11 million deal.

The Pittsburgh Steelers continue to fill out their roster with Sebastian Joseph-Day signing
Joseph-Day has never been a star by any means, but he has quietly become a strong run defender and capable pass rusher from the interior. He should be able to slot in as the primary backup at the 3-tech and 5-tech spots, giving defensive coordinator Patrick Graham the ability to spell Cam Heyward and Derrick Harmon without as much risk of the front caving in.
The former Rams sixth-round pick has been a starter for 90 of his 105 career games, so he can handle a sizable workload if needed. He may benefit from a smaller role now that he will be entering his age-31 season. While he hasn't played it much in recent years, he has enough size (6'4", 310 pounds) to kick into the nose tackle spot if need be.
Considering Pittsburgh already feels comfortable letting Keeanu Benton play NT (which is questionable at best), I don't see why Joseph-Day couldn't play there for them as well.
The signing does have the potential to bury guys like Yahya Black and Logan Lee on the depth chart, but neither has shown enough in their limited action to pass up a veteran addition.
It may also be a sign that the Steelers aren't in love with this year's interior defensive line class, which could mean the first draft under general manager Omar Khan that doesn't include one. For what it's worth, I tend to agree with that sentiment.
