The Green Bay Packers can begin the search for a new defensive coordinator.

The team fired long-time defensive coordinator Dom Capers on Monday, ending a nine-year run for one of the NFL’s longest-tenured coordinators. Green Bay finished 26th in points allowed in 2017.

The Packers should have several strong options to replace Capers in 2018, regardless of whether coach Mike McCarthy wants to promote from within or make an outside hire.

Here’s a quick look at the top candidates:

Vic Fangio: Veteran coordinator who knows Capers’ system as well as anyone in football. Led great defenses in San Francisco and helped rebuild Chicago’s defense in recent years. Would bring instant credibility to Packers defense.

Winston Moss: Long-time NFL player and Green Bay’s current associate head coach and linebackers coach. He’s reportedly receiving outside head coach interest. Has been in Green Bay coaching defense since 2006 and probably wants a bigger role.

Mike Nolan: Vast coordinator experience from several stops around the NFL. Currently the Saints linebacker coach. Packers coach Mike McCarthy was his offensive coordinator in San Francisco in 2005. Former head coach, like Capers.

Chuck Pagano: The Colts fired Pagano after six seasons leading the operation in Indianapolis. He coordinated the Ravens’ defense in 2011 and has years of experience coaching defense, especially in the secondary. Will be in high demand.

Darren Perry: Former All-Pro safety for Steelers defensive coordinator Dick LeBeau and the Packers current safeties coach. Might be ready for more responsibilities.

James Bettcher: Young and innovative coordinator who ran a hybrid system and got the most out of his players in Arizona. Will likely be available after Cardinals coach Bruce Arians retired Monday.

Joe Whitt Jr.: The Packers cornerbacks coach is a young, ascending coach known for developing and teaching. Could bring a new voice to the defense. However, he doesn’t have extensive experience coaching anything but the secondary.

Michael Barrow: Currently serves as the assistant head coach and linebackers coach for the Seahawks. Seattle’s version of Winston Moss. Former long-time NFL player who could be looking for his chance to lead his own defense.

Gus Bradley: Expected to be available after spending one year running the Chargers defense. He’ll be highly sought after by teams needing a new coordinator. Always offers tough, fast, aggressive defenses.

Mike Pettine: Failed as the Browns head coach but coordinated good defenses in New York and Buffalo. First developed as a coach in Baltimore and later followed Rex Ryan to the Jets.
