Seahawks work quickly to replace Gus Bradley; Rod Marinelli to leave the Bears

Seattle Seahawks defensive coordinator Gus Bradley accepted the head coaching position with the Jacksonville Jaguars on Thursday morning and Pete Carroll wasted little time finding his replacement. The Seahawks announced on Thursday afternoon that University of Florida defensive coordinator Dan Quinn will replace Bradley as the team's defensive coordinator.

Quinn, 42, coached the Seahawks defensive line from 2009-10 and played an integral role in turning around Red Bryant's career. A fourth-round pick out of Texas A&M in 2008, Bryant couldn't stay healthy or get on the field before the team moved him to defensive end in 2010. Bryant has developed into a run-stopping force and team leader, signing a five-year, $35 million contract extension with $14.5 million in guaranteed money last March. In addition to his work at Florida, Quinn has a lengthy history in the NFL, coaching defensive lines with the San Francisco 49ers (2003-04), Miami Dolphins (2005-06) and New York Jets (2007-08) before he was lured to the Pacific Northwest by former Seahawks head coach Jim Mora.

By hiring Quinn, the Seahawks have also protected against the potential departure of defensive line coach Todd Wash, who could follow Bradley to Jacksonville as a defensive coordinator.

In other defensive coordinator, newly-hired Chicago Bears head coach Marc Trestman announced that Rod Marinelli has decided to move on from the organization.

Seattle was a potential landing spot for Marinelli, who has been rumored to be headed to the Dallas Cowboys to coach the defensive line under Monte Kiffin. Marinelli was Kiffin's defensive line coach with the Tampa Bay Buccaneers from 1996-2005.

The Denver Broncos have settled on an offensive coordinator to replace Mike McCoy, who is now the head coach of the San Diego Chargers. John Fox has bypassed former Arizona Cardinals head coach Ken Whisenhunt and is promoting quarterbacks coach Adam Gase to coordinator.

“I absolutely think I’m ready and I’m not nervous about calling plays," Gase said during a conference call on Thursday. "You have one of the greatest quarterbacks of all time (Peyton Manning) as your quarterback—I’m excited. I’m thrilled to be able to have that opportunity. We’re looking to go pedal to the metal and play as fast as possible and be aggressive and score as many points as possible every game."

On Thursday, the Chargers announced that Whisenhunt would be the team's offensive coordinator.

Here's an update on the one head coaching vacancy and two general manager positions that remain open in the NFL:

Arizona Cardinals head coach: The Cardinals interviewed Seahawks offensive coordinator and Arizona native Darrell Bevell on Wednesday. Bevell was one of three finalists for the Bears' head coaching position, but GM Phil Emery cited his lack of experience as the reason he did not land the position. The Cardinals are expected to interview Indianapolis Colts offensive coordinator Bruce Arians this week, as well. The Cardinals have already interviewed current defensive coordinator Ray Horton, Cincinnati Bengals offensive coordinator Jay Gruden and Pittsburgh Steelers offensive coordinator Todd Haley.

Cleveland Browns general manager: The Browns added six coaches to Rob Chudzinski's staff, including hiring former San Diego Chargers head coach Norv Turner to be the team's offensive coordinator. Former Buccaneers head coach and current Washington Redskins defensive backs coach Raheem Morris is scheduled to interview for the team's defensive coordinator position. The team is still searching for a general manager, however, with Kansas City Chiefs director of player personnel Ray Farmer believed to be the in-house favorite. Other known candidates include Seahawks vice president of football administration John Idzik and Michael Lombardi, a former personnel executive with the Browns, San Francisco 49ers, St. Louis Rams and Philadelphia Eagles who is currently an analyst for the NFL Network.

New York Jets general manager: Reports out of New York have owner Woody Johnson down to three finalists to replace Mike Tannebaum, who was fired on Dec. 31. That list includes current assistant GM Scott Cohen, Seahawks vice president of football administration John Idzik and Pittsburgh Steelers director of football and business administration Omar Khan.

Former Atlanta Falcons director of player personnel David Caldwell reportedly spurned a $1 million housing allowance offer from the Jets and is now the GM of the Jaguars. Other candidates for the Jets' job include former Bears general manager Jerry Angelo, former Broncos general manager Ted Sundquist, Miami Dolphins assistant GM Brian Gaine, Montreal Alouettes GM Jim Popp, New York Giants director of college scouting Marc Ross and San Francisco 49ers director of player personnel Tom Gamble.
