Week one of NFL free agency has come and gone, and while it's very possible that in the middle of reading this, Pittsburgh signs another player, the initial wave has passed. 

Before the second tier of free-agent signings begins, I want to dissect every re-sign and free-agent pickup that Pittsburgh has achieved this week. 

Players will be graded on a regular A-F scale, with details and analysis as to why the move received the grade. Let's jump in. 

Re-signings 

Damontae Kazee: B+

Kazee is a solid safety who once lead the NFL in interceptions. Bringing him back on a two-year deal was a smart move, given the depth and ball-hawking ability he provides. 

With questions still lingering about the return of safety Terrell Edmunds, there's a chance that Kazee is elevated to a full-time starter in 2023. 

If so, this grade will deserve a bump given the structure of his salary. 

Larry Ogunjobi: A-

Ogunjobi returns to Pittsburgh on a three-year deal, with the full contract details still pending. 

His presence on the interior of the defensive line was noteworthy last season, a key catalyst in the run defense's improvement from 2021 to 2022. 

Still only 28 years old, this move allows Pittsburgh to play within the parameters of their 3-4 scheme, with Ogunjobi providing some pass rush help when necessary. 

Signings:

Patrick Peterson: A+

The future Hall of Fame corner signed a two-year deal with the Steelers and plans to end his career in black and gold. 

Still playing at a remarkably high level at the age of 32, Peterson's deal is essentially one year, with a fair value given his stature and accolades. 

With the departure of Cam Sutton to Detroit, Pittsburgh had to fill that hole while they look to groom a new corner coming out of the draft. 

Peterson's football IQ is off the charts at this stage of his career, making up for the slight erosion of athleticism in his game. Expect this all-time great to live up to the hype. 

Nate Herbig: B-

The Steelers needed to approach a free agency with the intent of adding to a rag-tag offensive line. 

So while Herbig isn't the big fish that the Steelers almost landed, he is a suitable interior offensive lineman that could compete for a starting role, with swing utility upside. 

A two-year deal with a maximum of $8 million in salary is feasible given his potential usage on the line. 

Cole Holcomb: A

With the departure of Robert Spillane, and the knowledge that Devin Bush was no longer going to be a Steeler, Pittsburgh desperately needed to address inside linebacker. 

Holcomb was the first of two additions at this critical defensive spot and in my opinion the better of the two. 

At 6'1 and 240 pounds, he is more reminiscent of the body types that Pittsburgh prefers at inside linebacker, while still having the athleticism to play off the edge or cover in the middle of the field. 

As we await the full terms of his three-year deal, it can be hypothesized that this was a slam dunk for both Pittsburgh and the 26-year-old up-and-comer. 

Elandon Roberts: C

The veteran linebacker signed a two-year deal earlier this week, with the full terms still pending. 

Seemingly replacing Myles Jack, the Steelers signed Roberts and released Jack shortly after, signaling a changing of the guard at the inside linebacker position. 

From a financial perspective, this move makes all the sense in the world. The problem is, Roberts is as one trick of a pony as it gets. 

Unlike Holcomb, he is a pure thumper, making him a liability in pass coverage. 

I understand the want to replace smaller faster linebackers with bigger, traditional ones, but positional flexibility is not black and white. 

Hopefully, Pittsburgh has something else up their sleeve, with eyes on a certain prospect in April's draft.
