The New York Jets have confirmed the hiring of Robert Nunn as defensive line coach.

A veteran of 11 seasons on an NFL sideline, Nunn was previously defensive line coach in Cleveland, who last season fielded the league’s second worst rush defense, allowing over 142 yards on the ground per game.

The Jets relieved Pepper Johnson from defensive line coaching duties as part of the wave of firings that saw five assistants leave the organization along with offensive coordinator Chan Gailey’s retirement.

Nunn has experience coaching 4-3 defensive alignments, whereas the Jets usually run a three-man front, though have been known to change their scheme in given situations, in particular to start the 2015-16 season when Sheldon Richardson returned from suspension. The Browns ran a 3-4 look with Nunn at the helm in 2016.

Defensive line is a relative strength on an otherwise weak roster: end Muhammad Wilkerson signed an $86 million contract last offseason, though his production in the months since then failed to live up to that amount, while second year end Leonard Williams looks to be one of the team’s few promising features on defense.

The Jets fielded the No. 11 run stop this season.
