Brian Daboll was hired recently to run the offense, which led many to question whether Zorn would be back. He was retained along with assistant head coach Maurice Carthon, tight ends coach Bernie Parmalee, strength coach Mike Clark, wide receivers coach Nick Sirianni and virtually the entire defensive staff.
Jack Bicknell Jr. was hired to coach the offensive line and Jim Bob Cooter was brought in as the offensive quality control coach. Tom McMahon and Derius Swinton will handle special teams.
"We were able to add a handful of strong additions to an already talented group of coaches, and I am excited to get started," Crennel said in a statement issued by the team.
Many believed that Zorn was the front-runner for the offensive coordinator position, but Crennel eventually opted to go with Daboll, whom he coached with in New England.
Besides bringing in a fresh face to run the offense, a new special teams staff and a new offensive line coach to replace the retired Bill Muir, Crennel largely opted for continuity in filling out the rest of his coaching staff.
Linebackers coach Gary Gibbs, defensive line coach Anthony Pleasant, defensive quality control coach Otis Smith, defensive backs coach Emmitt Thomas and defensive assistant Adam Zimmer all worked under Crennel last season, when he was the defensive coordinator for Todd Haley.
Crennel plans to remain the coordinator after assuming the permanent head coaching job.
