The Bears made official the completion of Nagy’s staff with an announcement Tuesday, unveiling a list of coaches with unique backgrounds in the NFL and the college ranks.

Quarterbacks coach Dave Ragone is the only incumbent coach on offense, returning for a third season to the position. Internally, he was viewed as a key figure in the growth of 23-year-old quarterback Mitchell Trubisky last season, helping the rookie fine-tune his game and accelerate his development.

Nagy tabbed former Oregon coach Mark Helfrich as his offensive coordinator in January, one of his first hires. Charles London, previously with the Texans, will coach the running backs. Former NFL receiver Mike Furrey left a job as head coach of Division-II Limestone College to become the receivers coach. Nagy also landed a big hire with respected offensive line coach Harry Hiestand, who most recently worked at Notre Dame before returning for a second stint to the Bears. Kevin Gilbride Jr. will work with the tight ends.

The Bears were thrilled to retain defensive coordinator Vic Fangio, who operated the defense for the past three seasons under former head coach John Fox. Under the watch of Fangio, the Bears defense rose inside the top 10 in both points and yards allowed per game.

As Fangio expected, the Bears retained his entire defensive coaching staff, with defensive line coach Jay Rodgers, outside linebackers coach Brandon Staley, inside linebacker coach Glenn Pires and defensive backs coach Ed Donatell back.

Chris Tabor, formerly of the Browns, was hired by the Bears to continue working as their new special teams coordinator. He replaced Jeff Rodgers, who worked three seasons on Fox’s staff.

A major change for the Bears coaching staff comes with a new strength and conditioning coach. The team dismissed Jason George and hired Jason Loscalzo from Washington State in that capacity. Andre Tucker will take his 15 years of NFL experience to the Bears as their new trainer, replacing Nate Breske. The Bears are hoping for better health in Nagy’s tenure after injuries took their toll the last two seasons.

The Bears also announced that Brad Childress will serve as a senior offensive consultant, a position in which he will work closely with his good friend Nagy.
