The Bears have relieved offensive coordinator Mike Tice of his duties, according to a league source.
In fact, they fired the entire offensive staff: quarterbacks coach Jeremy Bates, running backs coach Tim Spencer, offensive line coach Tim Holt, receivers coach Darryl Drake and tight ends coach Mike DeBord.
On the defensive side of the ball, only linebackers coach Bob Babich was relieved of his duties.
On the team's official website, defensive backs coach Jon Hoke, assistant defensive backs coach (safeties) Gil Byrd and defensive line coach Mike Phair were still listed on the coaching staff, along with strength and conditioning coach Jim Arthur and strength and conditioning coordinator Rusty Jones.
The Bears also reportedly hired former Dallas Cowboys running backs coach Skip Peete.
Initially hired as the team's offensive line coach in 2010, Tice was promoted to offensive coordinator after the ouster of Mike Martz during the 2012 offseason. But the Bears offense struggled in 2012, ranking 28th in total yards and 29th passing the ball.
Although under contract through 2013, Tice's future was essentially set when the Bears immediately hired Aaron Kromer from the New Orleans Saints to serve as the offensive coordinator/ offensive line coach.
New Bears coach Marc Trestman tried to convince defensive coordinator Rod Marinelli to remain on the staff but he elected to leave for a fresh start. Marinelli, who was a close friend of former Bears coach Lovie Smith, is expected to become the Dallas Cowboys defensive line coach. Monte Kiffin, another of Marinelli's friends, recently was named the defensive coordinator there.
Trestman started meeting with other Bears assistants still under contract today after his introductory press conference.
