So far, the Panthers’ biggest defensive move in 2019 free agency has been signing former Falcons defensive end Bruce Irvin.

Irvin was part of a stupendous 2012 draft class for the Seahawks that included Russell Wilson and Bobby Wagner. He played an integral role in helping them get to two Super Bowls. During his 2.5 years playing in Oakland, Irvin’s play was respectable if not outstanding. He finished the 2018 season on a high note after being released and signing with Atlanta, posting 3.5 sacks in his last four games.

Some would argue that Irvin’s game is in serious decline, though. According to Pro Football Focus, Irvin’s rating has dropped significantly since 2016, falling from a 75.0 grade (ranking No. 31 in the NFL) to a 59.0 last season, ranking him No. 88 out of 111 defenders with enough snaps to qualify.

Can Bruce Irvin have a bounce-back year with the #Panthers in 2019? He posted a career-low overall grade (59.0) playing for Oakland and Atlanta last season.

While it’s fair to suggest that Irvin is not the same player he was from 2012-2015 in Seattle, this doesn’t mean he’s going to be a bust for Carolina.

For one thing, Irvin might have had a stronger grade with the Raiders if they had not traded Khalil Mack away to the Bears. With Mack drawing double and triple teams in Chicago, it was much easier for opposing teams to contain Irvin during the first half of 2018.

Atlanta’s edge rotation didn’t offer much of an upgrade, either. Takk McKinley ranked No. 70 and Vic Beasley was dead last.

Adrian Clayborn – 50th of 103

Takkarist McKinley – 70th of 103

Vic Beasley – 103rd of 103 — PFF ATL Falcons (@PFF_Falcons) April 10, 2019

While the Panthers don’t have a difference-maker like Mack, their edge depth chart is in better shape than either Oakland or Atlanta’s, so it should be easier for Irvin to make an impact in Charlotte.

Irvin is also going to be in a somewhat different role in Carolina. He was primarily an edge for the Raiders and Falcons, but part of the reason he signed was the role Ron Rivera has in mind for him, which will include Irvin playing some linebacker as well, which is his more natural position.

Even if Irvin really is on the decline and has a mediocre season, the Panthers will only be paying him up to $4 million on a one-year deal.
