The Chicago Bears will hire Mel Tucker to become their next defensive coordinator.

Tucker will place Rod Marinelli in the position.

Tucker was most recently defensive coordinator of the Jaguars.

The NFL appears to be in a cycle where franchises are looking for offensive head coaches. They have also been uniformly white men this offseason.

The NFL had eight head coach openings this offseason and all six of the hires have been by white men lauded for their ability to coach on offense.

Andy Reid (Chiefs), Doug Marrone (Bills), Rob Chudzinski (Browns), Mike McCoy (Chargers), Marc Trestman (Bears) and Chip Kelly (Eagles) have all been hired. 

The favorites for the final two positions are Bruce Arians for the Cardinals and Greg Roman for the Jaguars.

All of the general manager hires have also been white men.

The NFL requires the interview of at least one minority candidate for every head coach and GM position.

The Chicago Bears have hired Marc Trestman as head coach.

Trestman comes from the Canadian Football League's Montreal Alouettes.

Trestman has been an assistant with eight NFL teams, but has been out of the league for eight years. He is noted as a quarterback guru.

Trestman will bring in former Saints interim head coach Aaron Kromer as offensive coordinator and offensive line coach, a league source told ESPN.

Phil Emery hopes to bring back defensive coordinator Rod Marinelli.

Bruce Arians has several head coaching interviews in the coming days.

Arians will meet with the Chicago Bears on Sunday, San Diego Chargers on Monday and Philadelphia Eagles on Tuesday.

Arians served as offensive coordinator of the Indianapolis Colts this season.

The Chicago Bears will interview Mike Singletary and Mike Priefer for their head coaching vacancy.

The Bears have also interviewed Dave Toub.

Singletary had an 18-22 record with the 49ers.

The Chicago Bears will interview Darrell Bevell, according to a source.

Bevell is currently the offensive coordinator of the Seattle Seahawks.

Bevell was also offensive coordinator of the Minnesota Vikings from 2006 to 2010 where he worked with Brett Favre.

The Chicago Bears have requested permission from the Indianapolis Colts to interview offensive coordinator Bruce Arians.

The San Diego Chargers are also interested in Arians.

Arians assumed head coaching duties of the Colts during Chuck Pagano's absence.

The decision to fire Lovie Smith was made due to inconsistency on offense and the Chicago Bears' inability to perennially advance to the postseason.

"During the course of Smith's career, we've had one offense that ranked in the teens (in 2006, when the Bears advanced to the Super Bowl). We haven't had the balance between our defensive excellence," GM Phil Emery said during a Tuesday press conference. "We have searched for answers. The end result is we did not have enough consistency. That, paired with not getting into the playoffs on a consistent basis, I made the change moving forward."
