If we've learned one thing about NFL owners over the past few years, it's that they don't waste anytime anymore when it comes to firing a coach.

Five head coaches were given their pink slips within 24 hours of the end of the regular season, with a sixth deciding to call it a career out in the desert. Will Brinson has all the winners and losers from the first day of the coaching carousel in his Black Monday scorecard, and you can find all you need to know about the following weeks of coaching carousel action below.

To keep you up-to-date on the latest firings, rumors and hirings, here's our coaching tracker for the 2018 offseason.

AFC

Retired: Defensive coordinator Dean Pees calls it a career

Promoted: Wink Martindale takes over DC role

Dean Pees has been coaching in some form or another since 1979. He worked his way up from the Division II Findley Oilers to the NFL, where he's been coaching since 2004. He worked as a linebackers coach and then defensive coordinator for the New England Patriots, then did the same thing for the Baltimore Ravens. On Monday, he announced his retirement.

Pees was the fourth coach to serve as defensive coordinator under John Harbaugh, following Rex Ryan, Greg Mattison, and Chuck Pagano. The fifth will be Don "Wink" Martindale, who was promoted from his role as linebackers coach.

Staying: Marvin Lewis gets new contract with Bengals

Although it had been reported since mid-December that Marvin Lewis was done in Cincinnati, it looks like he's going to stay. Lewis and the team have agreed to terms on a new two-year deal that will keep him with the Bengals through the 2019 season. It's somewhat surprising that he's staying, but not totally shocking. Lewis spent the past three weeks claiming that no decision had been made and that was clearly the case here.

After watching the Bengals close their regular season on a two-game winning streak, Lewis showed up to his end-of-season press conference on Monday and sounded like a guy who was very interested in staying. One of his first moves was replacing defensive coordinator Paul Guenther, who took the same role with Oakland, with former Lions defensive coordinator Teryl Austin.

Cleveland Browns

Report: Hue Jackson is safe

Browns owner Jimmy Haslam already promised Hue Jackson that he would be returning for 2018, and he seems to be standing by that promise. After the Browns lost to the Steelers 28-24 on Sunday to fall to 0-16, Haslam once again reiterated his support for Jackson, who is now 1-31 in two years with the Browns.

The only question now is whether or not Haslam actually sticks to his word over the next few days. With the hiring of new general manager John Dorsey, it wouldn't be a shock to see Dorsey convince Haslam that it would make way more sense for Dorsey to hire his own coach.

Safe: Vance Joseph staying in Denver

Although the Broncos had given some thought to dumping Joseph after just one season, general manager John Elway has decided to keep Joseph around for at least one more season. CBS Sports NFL Insider Jason La Canfora reported that Elway "went back and forth on the decision" before eventually making the call to keep Joseph on Monday. Joseph's first season with the Broncos ended with a 5-11 record, but it's hard to blame him for that, especially when you consider that he was given a roster that doesn't really feature an NFL-caliber starting quarterback. The argument for firing Joseph was that the Broncos had been downright bad in several games this year. The Broncos had four losses by 20 or more points in 2017, which is more than the 0-16 Browns, who have only lost one game by 20 or more points.

Report: Bill O'Brien is at odds with general manager Rick Smith, but will stay in Houston for 2018

Although Bill O'Brien and Rick Smith reportedly have a "toxic" relationship, that doesn't look like it's going to be an issue going forward. The Texans announced on Sunday that Smith will be taking a leave of absence to help care for his wife, who was recently diagnosed with breast cancer. With Smith out of the picture for now, the Houston Chronicle reports that O'Brien will "definitely" be returning to the Texans in 2018. This is good news for Deshaun Watson, who recently made it clear in a tweet that he wants the team bring O'Brien back next season.

Fired: Chuck Pagano is out

In: Josh McDaniels a virtual lock to take over in Indy

Josh McDaniels is a virtual lock be the next coach of the Indianapolis Colts, CBS Sports NFL insider Jason La Canfora reports. The Colts were the first team to interview McDaniels during this turn of the coaching carousel, and despite the Titans becoming a surprise entry into the coaching market on Monday, the Patriots offensive coordinator will take the reins in Indianapolis once New England's playoff run is over.

The Colts fired previous coach Chuck Pagano less than 90 minutes after the team's Week 17 win over the Texans.

Kansas City Chiefs

Promoted: Eric Bieniemy takes over as OC

After the Chiefs lost Matt Nagy to the Bears as Andy Reid's offensive coordinator bolted for an opportunity to serve as Chicago's head coach, the Chiefs quickly moved to fill his position, promoting running backs coach Eric Bieniemy to the OC role.

"I've known Eric a long time, both as a player and a coach," Reid said in a statement. "He's done a phenomenal job with our running backs and has been involved in every aspect of our offense over the last five years. He's a great teacher and has earned this opportunity. I know he will do a good job."

Bieniemy coached the running backs in Minnesota from 2006-10, working closely with Adrian Peterson. He then spent two years as the offensive coordinator for Colorado at the collegiate level before returning to the NFL to coach the Chiefs running backs for the past five seasons.

Fired: Jack Del Rio is out

Hired: Jon Gruden signs massive deal to coach Raiders

One year after ending the Raiders' 13-season playoff drought, Jack Del Rio has already been kicked to the curb. After the Raiders' 30-10 loss to the Chargers on Sunday, Del Rio announced that he's been fired and in something that came as a surprise to absolutely no one, Jon Gruden has been hired to replace him.

To lure Gruden out of the ESPN broadcast booth, the Raiders gave him a 10-year deal that will be worth up to $100 million. Although the Gruden hire makes plenty of sense for the Raiders, there's no guarantee that it's going to work out. Gruden has coached since 2008 and hasn't won a playoff game since leading the Buccaneers to a win in Super Bowl XXXVII.

Hired: Mike Vrabel takes the reins in Tennessee

After the Titans shockingly did an about face on their decision to retain Mike Mularkey, the team settled on a new head coach less than a week after their playoff loss to the Patriots: Texans defensive coordinator Mike Vrabel.

Vrabel's had a meteoric rise up the coaching ranks, retiring from the NFL after the 2010 season and immediately jumping into coaching. He worked under Urban Meyer at Ohio State (his alma mater) from 2011 through 2013 as both the linebackers and defensive line coach with Ohio State before jumping to the NFL.

The former All-Pro linebacker and three-time Super Bowl winner joined the Houston Texans coaching staff as the linebackers coach -- with his former defensive coordinator Romeo Crennel -- in 2014 serving in that role until this year when he was promoted to defensive coordinator (Crennel was bumped to assistant head coach under Bill O'Brien).

"Everything we do is going to be geared towards winning and being physical," Vrabel said in a statement announcing the hire. "We want to prepare our players so they know what to do, which will allow them to play fast and aggressive."

NFC

Sunset: Bruce Arians calls it a career

Hired: Cardinals tab Steve Wilks to replace Arians

After a highly successful coaching career with the Cardinals, Bruce Arians is ready for retirement. Arians announced his decision to walk away in an understandably emotional press conference on Monday.

Arians has had some health scares over the years -- including two hospital trips in 2016 -- which might have played a factor in his decision to retire. CBS Sports NFL Insider Jason La Canfora reported in early December that Arians was leaning toward retirement and that the team began making "internal preparations" for his departure at the time.

The Cardinals, who were the last of six teams to fill their head-coaching opening, have chosen Panthers defensive coordinator Steve Wilks to take over for Arians in Arizona. You can read all about the hire here.

Fired: John Fox is out

Extended: Ryan Pace remains as GM

Hired: Matt Nagy is the new head coach in Chicago

After three straight seasons of not topping the six-win mark, the Bears have finally had enough of John Fox. Although the team dumped Fox, they decided to hold on to general manager Ryan Pace, who was given a four-year extension on Jan. 1, which now gives him the opportunity to continue building his vision of a winner in Chicago despite posting a 14-34 record over the last three seasons.

The first decision Pace made under his new deal was the hiring of Nagy as the team's new coach. The upcoming season will mark Nagy's first year as a NFL head coach. Before signing on with the Bears, Nagy served as an offensive coordinator (2016-17) and quarterbacks coach in Kansas City (2013-15). Before that, Nagy worked with the Eagles, where he held various jobs since first being hired by the team in 2008.

Report: Jason Garrett isn't going anywhere

Unless Jerry Jones has a sudden change of heart, it looks like Jason Garrett's job is safe in Dallas. During a radio interview the day after Christmas, the Cowboys owner said that he would be keeping Garrett for the 2018 season. "I certainly know a lot about Jason Garrett. Because of that, I can quickly and candidly say his job is not an issue here, at all," Jones said on Tuesday. "It's not in the best interest of the Cowboys to be considering a coaching change."

Considering everything that Garrett had to deal with this year -- from the injuries to the Ezekiel Elliott situation -- it's no surprise that Garrett is sticking around, especially when you consider that the Cowboys are coming off a 13-3 season in 2016.

Fired: Jim Caldwell is out

In: Matt Patricia expected to be next Lions coach

Matt Patricia is a virtual lock to be the next coach of the Detroit Lions, CBS Sports NFL insider Jason La Canfora reports.

Patricia, 43, has served as the Patriots defensive coordinator for the last six seasons, and in each New England finished in the top 10 in points allowed. That includes 2017, a season where the Patriots took a lot of heat for a defense that gave up plenty of yardage but still finished fifth in points allowed.

Patricia will join a Lions team with a familiar face on the personnel side in general manager Bob Quinn, who spent 16 years in the Patriots organization before being hired by the Lions two years ago. Patricia will be taking over for Jim Caldwell, who went 36-28 in four seasons with the Lions that included two trips to the playoffs and three years above .500.

Green Bay Packers

Reports: Packers make change at GM, defensive coordinator

It hasn't been formally announced just yet, but longtime Packers DC Dom Capers was fired following the team's Week 17 game, according to ESPN's Rob Demovsky.

Capers had been with the team since 2009, but the Packers had not ranked inside the top 10 in yards or points allowed since his second season as coordinator. The Green Bay defense struggled with injuries the last couple seasons, but the team apparently feels that it's time to change the voice giving the instructions on that side of the ball.

While that news was big coming out of Green Bay, the report that GM Ted Thompson would transition to a different role in a front-office shakeup was enormous for an organization that has been one of the most conservative in football. Thompson, the man who drafted Aaron Rodgers, began his run as the team's GM in 2005.

With Thompson out of the GM role, the Packers decided to shake up the structure of the personnel department. Brian Gutekunst has been named general manager, with Russ Ball being promoted to executive vice president/director of football operations. Both men, along with coach Mike McCarthy, will report directly to team president and CEO Mark Murphy.

In: Pat Shurmur expected to take over for Giants

It appears new Giants general manager Dave Gettleman has settled on his first head coaching hire, as Vikings offensive coordinator Pat Shurmur is expected to be named Giants head coach after his current team's playoff run is over, CBS Sports NFL insider Jason La Canfora reports.

Shurmur, 52, spent two seasons in Cleveland in 2011-12, guiding the Browns to a 9-23 record. He served as the offensive coordinator of the Eagles for the next three years and coached the team on an interim basis for one game in 2015 after Chip Kelly was fired. Shurmur then joined the Vikings as tight ends coach in 2016 but was promoted to interim offensive coordinator, replacing Norv Turner midseason. He reprised that role this season, leading an offense centered around less heralded players like Case Keenum and Adam Theilen for much of the season.

Report: Dirk Koetter isn't going anywhere

Although there had been rumors that Jon Gruden might be a candidate for this job, it looks like Koetter will definitely be sticking around for at least one more season. The family that owns the Bucs told Koetter on Friday that he'll be retained for at least the 2018 season. According to NFL.com, the Bucs went after Gruden and got rebuffed, which is likely why they gave Koetter a vote of confidence out of nowhere on Friday.

Report: Jay Gruden's job is safe

One team that won't be looking for a new head coach this offseason is the Washington Redskins. According to NFL.com, the Redskins plan on keeping Gruden going forward. Of course, the downside of this for Gruden is that he'll likely open the 2018 season on the hot seat. Since taking over the Redskins' job in 2014, he's posted a 28-34-1 record with one playoff appearance, although he has had to deal with the annual offseason drama that the Kirk Cousins situation has turned into. If, for some reason, Redskins owner Daniel Snyder were to change his mind and dump Gruden, the Redskins coach would instantly become a top candidate for the Bengals' job.
