The third piece of coach Marc Trestmans senior team clicked into place late Friday when former Jacksonville Jaguars defensive coordinator Mel Tucker was selected as defensive coordinator.
The step leaves out current defensive backs coach Jon Hoke and two college candidates as Trestman continues to lean on the NFL for his top staff additions.
Tucker joins offensive coordinator Aaron Kromer from New Orleans and special teams coordinator Joe DeCamillis from Dallas as the heads of the three phases of Bears on-field ops.
The Tucker hiring was part of a handful of hirings Friday. Dallas running backs coach Skip Peete was signed to replace Tim Jennings as Bears running backs coach.
Andy Bischoff, from Trestmans staff with the Montreal Alouettes, was hired as Bears tight ends coach. Michael Sinclair, defensive line coach with the Alouettes, joins Trestmans staff as assistant defensive line coach.
The Tucker move raised some eyebrows around the NFL because of the abysmal 2012 season that the Jacksonville defense suffered through. The Bears ran up 41 points on the Jaguars in their Oct. 7 game in Jacksonville with a season-high 501 yards and three offensive touchdowns. Jacksonville tied for 29th in scoring defense with nearly 28 points per game. The Jaguars were 28th in yardage allowed and 27th in scoring defense in 2010.
Before his stint in Jacksonville, Tucker was defensive backs coach for the Cleveland Browns from 2005-07 before being promoted to defensive coordinator in 2008 after the firing of Todd Grantham. When the Browns went 4-12, Tucker was let go along with the rest of coach Romeo Crennels staff.
Tucker was co-defensive coordinator at Ohio State in 2004 and was defensive backs coach when the Buckeyes won the national championship in 2002. Before Ohio State he was a member of Nick Sabans staffs at LSU and Michigan State.
