The 49ers' hire of Jim O'Neil as their defensive coordinator officially shut the coaching carousel down for 2016. There are still some positional coach openings to fill, but, for the most part, coaching staffs are set. Here is a rundown of the biggest changes across the league.
The AFC rundown can be found here.
Last Update: 1/27/2016 4 p.m. EST
Make sure to bookmark the Rotoworld News Page for up to the second breaking news. I also occasionally tweet about football @RMSummerlin.
The Lions became the first organization to fill their general manager vacancy when they nabbed former Patriots director of pro scouting Bob Quinn. Only 39, Quinn had spent his entire career in New England and spent the last three seasons directing the pro scouting department. His player evaluations are reportedly highly regarded.
Quinn’s first task as general manager was deciding coach Jim Caldwell’s fate. After a week of deliberation, Quinn decided to keep Caldwell around for another season, but it is likely he will be a short leash under a general manager who did not hire him. Keeping Caldwell around was a good idea simply to retain the services of OC Jim Bob Cooter and DC Teryl Austin. Cooter worked wonders with Matthew Stafford over the second half of the season, and Austin is a well-respected coordinator who should land his own head coaching job soon enough.
GM Bob Quinn: With the patriots from 2000-2015. Worked his way up from player personnel assistant to the director of pro scouting.
HC Jim Caldwell: 18-14 in two years in Detroit with one playoff appearance. Rebounded from a 1-7 start to finish 7-9.
OC Jim Bob Cooter: Took over for Joe Lombardi Week 8. Matthew Stafford had a 20:4 touchdown-to-interception ratio under Cooter.
DC Teryl Austin: Finished 18th in total defense and 23rd in points allowed after finishing 2nd and 3rd respectively in 2014. Despite the slip, Austin did well to maintain some respectability despite a severe decrease in talent.
The Eagles did not bring in a new organization per se, but the firing of Chip Kelly and re-empowerment of Howie Roseman represents a significant change. Roseman will not take on the general manager title he lost in a power struggle with Kelly last offseason, but it does appear he will handle most of the duties usually reserved for the general manager. Even if they hire a new GM, that person would likely just be an advisor for Roseman.
On the coaching front, the Eagles gave courtesy interviews to former-OC Pat Shurmur and longtime Eagles player and assistant Duce Staley, but they ultimately decided to head in another direction. That said, the coaching search was not smooth.
Texas A&M coach Kevin Sumlin rebuked Philly early in the process. Bears OC Adam Gase was an early favorite, but he ended up in Miami. There were rumors of Jon Gruden being interested, but he refuted those reports. Owner Jeffrey Lurie was reportedly smitten with John Harbaugh, but that was as fanciful as a C.S. Lewis novel. Giants OC Ben McAdoo was thought to be a favorite, but he stayed in New York as the head coach. McAdoo's former boss Tom Coughlin was reportedly deep into negotiations, but he pulled his name out of the running because he did not feel he could build a staff on the fly with most of his people still under contract in New York.
After all of those whiffs, Philadelphia finally landed their man in Chiefs OC Doug Pederson. An Andy Reid acolyte, Pederson started nine games at quarterback for the Eagles in 1999 and was a coach with the organization from 2009-12 before following Reid to Kansas City as the offensive coordinator. Pederson was not the main play caller in Kansas City under Reid, but Reid did give him those duties at times to get him ready for his head-coaching future. Now heading his own team, Pederson will take on the play-calling duties.
Ex-Lions coach Jim Schwartz became the first member of Pederson's staff when he was hired as defensive coordinator. Schwartz was out of the league last season, but he led a dominant Bills defense in 2014. Philadelphia will likely switch to a 4-3 under Schwartz.
Ex-Chargers OC Frank Reich was hired as the offensive coordinator. He was scapegoated despite the Chargers offense arguably overachieving the last two seasons. RBs coach Duce Staley will be retained. Ex-Browns OC John DeFilippo was brought in as the QBs coach.
GM Howie Roseman: Served as the general manager in 2013 and 2014. Played a large role in the drafting of Marcus Smith in the first round in 2014.
HC Doug Pederson: Played and coached in Philadelphia.
OC Frank Reich: Chargers finished 9th in total yards despite serious injury issues.
DC Jim Schwartz: Led the Bills defense in 2014. Finished 4th in total defense and 4th in points allowed. Runs a 4-3 scheme.
New York Giants
Tom Coughlin “resigned” on Black Monday, although his brush off of John Mara at the press conference announcing his resignation and his willingness to speak with the Eagles and 49ers suggested there was more to the situation. Either way, the Giants had to search for a new coach.
New York considered several outside candidates, with Lions DC Teryl Austin, Panthers DC Sean McDermott, ex-Falcons coach Mike Smith and Jaguars assistant HC Doug Marrone getting interviews. The best candidate, however, was already inside the organization.
Eli Manning consistently expressed his desire for OC Ben McAdoo to become the new head coach, and the quarterback got his wish in the second week of the coaching search. McAdoo is extremely young as head coaches go at 38, and he has only two years of coordinator experience. Even so, Manning has played some of his best football under McAdoo the last two seasons, and McAdoo was clearly on the head coach track. Speeding up his ascension to a lead job is a small price to pay for the continuity the star quarterback obviously desired.
DC Steve Spagnuolo was passed over for the head job and got some interest from the Eagles, but he will remain as the defensive coordinator. It is an interesting decision considering how terrible Spags' defenses have been in his last two seasons as a coordinator (Giants in 2015 and Saints in 2012), but he was dealing with a talent-deficient roster last season. Perhaps he can turn it around, but he is going to need a talent infusion to make it happen.
Ex-Dolphins coach Joe Philbin was expected to join McAdoo's staff as the offensive coordinator, but that job went to QBs coach Mike Sullivan. Philbin ended up joining the Colts as an offensive line coach. Ex-Rams OC Frank Cignetti was hired to replace Sullivan.
GM Jerry Reese: Held the position since 2007. The lack of talent and depth on defense falls squarely on his shoulders.
HC Ben McAdoo: Finished 8th in total offense and 6th in points scored. Eli Manning has thrown at least 30 touchdowns with a 2.3 interception percentage in back-to-back seasons.
OC Mike Sullivan: Offensive coordinator with the Bucs in 2012 and 2013. Spent nine seasons total with the Giants including as QBs coach last year.
DC Steve Spagnuolo: Finished 32nd in total defense and 30th in points allowed. Led one of the worst defenses of all time while with the Saints in 2012.
San Francisco 49ers
Jim Tomsula was fired before the final fan made it out of the parking lot after the 49ers’ overtime win over the Rams in Week 17. Never a long-term answer, Tomsula will return to his rightful place as a position coach, and GM Trent Baalke will continue his attempt to ruin a franchise which was a legitimate contender as recently as 2013.
In that pursuit, Baalke was reportedly looking to hire a coach who would not "threaten [his] power." The paranoia likely caused San Francisco to miss out on Hue Jackson, who ended up in Cleveland, but the 49ers did land ex-Eagles coach Chip Kelly. Kelly has said he is no longer interested in running the personnel side after failing miserably in Philadelphia, and he reportedly has a good relationship with 49ers senior personnel executive Tom Gamble.
With Baalke at the helm, Kelly is probably the best possible outcome for the 49ers. He had success the first two years in Philadelphia, runs an offense which is a good fit for both Colin Kaepernick and Carlos Hyde, and is unlikely to seek out absolute power anytime soon. The defense in San Francisco played well at times in 2015. If Kelly can get the offense to be respectable, there is some hope for a turnaround.
Current DC Eric Mangini was expected to stick around, but Texans LBs coach and former All-Pro linebacker Mike Vrabel was offered the job. He declined, and the 49ers had to turn to ex-Browns DC Jim O'Neil. Cleveland's defense was bad with O'Neil running the show, and coaching opposite Kelly's fast-paced offense has proven to be a major challenge. The defense will face a ton more plays and will likely take a step back this season.
Curtis Modkins was brought in as offensive coordinator. He was Chan Gailey's coordinator in Buffalo from 2010-12 and spent the last three seasons coaching the running backs in Detroit. Kelly will call his own plays. Bob Bicknell came over from the Eagles to fill the same WRs coach role on 49ers.
GM Trent Baalke: Held the position since 2011. Had some hits in the 2014 draft, but his overall record is poor.
HC Chip Kelly: 26-21 in three seasons with the Eagles. Excellent fit for both Colin Kaepernick and Carlos Hyde.
OC Curtis Modkins: Bills offensive coordinator from 2010-12.
DC Jim O'Neil: Browns finished 23rd and 27th in total defense his two years as coordinator.
Tampa Bay Bucs
The firing of Lovie Smith was not shocking considering he was 8-24 in two seasons with the Bucs, but the timing was interesting. Tampa Bay waited until the Wednesday after Week 17 to let the veteran coach go, and that decision did not appear to be made until OC Dirk Koetter started to receive interest from other teams.
The timeline suggested Koetter was always the lead candidate for the job, and the Bucs made it official just over a week later. Koetter has had success as a play caller in his career, but his head-coaching experience is limited to the college ranks. That said, he appeared to be a hot candidate before Tampa decided to let Smith go. The Bucs obviously wanted to keep Koetter, and the only way that was going to happen was by making him the head coach.
Koetter brought in ex-Souther Miss coach Todd Monken as offensive coordinator, but he is expected to keep calling plays. He said he plans to be more aggressive next season. Monken will also coach the receivers.
Ex-Falcons coach Mike Smith, who was Koetter's boss in Atlanta, will join the staff as defensive coordinator. Smith's defenses early in his run as coordinator in Jacksonville were strong, but his defenses struggled late in his run with the Jags and throughout his tenure in Atlanta. Tampa Bay overachieved a bit in 2015, and there is a chance they take a step back next season under Smith.
GM Jason Licht: Held the position since 2014. Licht appears to have gotten it right with Jameis Winston at No. 1 overall in the last draft, and he found some later-round value in Kwon Alexander. Licht was behind the questionable decision not to exercise the fifth-year option on Doug Martin last spring.
HC Dirk Koetter: Finished 5th in total offense and 20th in points scored. Worked well with Winston, which is the main reason he was such a strong candidate for Tampa. Will continue to call plays as head coach.
OC Todd Monken: Coordinator and head coaching experience limited to college, but coached with Koetter in Jacksonville.
DC Mike Smith: Jags DC from 2003-07. Coached Falcons from 2008-14. Defenses have struggled most of the last seven seasons.
As expected, the Bears elevated former QB coach Dowell Loggains to offensive coordinator with Adam Gase now in Miami. Loggains appears to be a favorite of Jay Cutler, which likely helped him land the job. Loggains is now faced with the difficult task of building on the gains Cutler made under Gase.
GM Ryan Pace: First year in the position. Pace spent 14 years in New Orleans, serving the final two seasons as director of player personnel.
HC John Fox: 6-10 in his first season with Chicago. 125-99 in with two Super Bowl appearances in 14 years as a head coach.
OC Dowell Loggains: Mediocre as the Titans coordinator in 2013. Has a good relationship with Jay Cutler.
DC Vic Fangio: Finished 14th in total defense and 20th in points allowed. Architect of the dominant 49ers defense under Jim Harbaugh.
New Orleans Saints
Sean Payton was rumored to be on the market, but he and GM Mickey Loomis decided to keep moving forward together. New Orleans made their coordinator change when they fired DC Rob Ryan in November. Dennis Allen took over, but the defense did not improve. It is possible the Saints look to bring in a new coordinator.
GM Mickey Loomis: Held the position since 2002. New Orleans should again lead the league in dead cap in 2016.
HC Sean Payton: 87-57 with a Super Bowl championship in nine seasons. 14-18 over the last two seasons.
OC Pete Carmichael: Finished 2nd in total offense and 8th in points scored. Has finished top six in total offense every year since 2009.
DC Dennis Allen: Finished 31st in total defense and 32nd in points allowed. His teams have finished in the bottom 10 of points allowed in his five seasons as a coordinator or head coach.
St. Louis Rams
Unsurprisingly, the combination of Frank Cignetti and Rob Boras did not produce offensive magic, although Nick Foles certainly did not help. Cignetti was fired in December, but Boras is expected to be retained after steadying the ship.
GM Les Snead: Held the position since 2012. Acquired Nick Foles and gave him a two-year extension with $14 million guaranteed before he played a down in St. Louis.
HC Jeff Fisher: 27-36-1 in four seasons with no playoff appearances. There is no reason he should still have a job.
OC Rob Boras: Steadied the ship after Cignetti was fired.
DC Gregg Williams: Finished 23rd in total defense and 13th in points allowed. Seriously hampered by injuries throughout the defense in the second half of the season.
With Dirk Koetter landing the Bucs job, it is like OC Harold Goodwin stays in Arizona another season.
GM Steve Keim: Held the position since 2013. The most active GM in the league, Keim has hit on several veteran reclamation projects in the last couple seasons. Dwight Freeney, Chris Johnson and D.J. Swearinger have all contributed this year.
HC Bruce Arians: 34-14 with two playoff appearances in three seasons. Has won the Coach of the Year award two of the last four seasons.
OC Harold Goodwin: Finished 1st in total offense and 2nd in points scored.
DC James Bettcher: Finished 5th in total defense and 7th in points allowed in the first year as a coordinator.
Both OC Mike Shula and DC Sean McDermott emerged as candidates, but they are unlikely to land a promotion this cycle with almost all the jobs taken. Both will be names to watch again next season.
GM Dave Gettleman: Held the position since 2013. Has made several questionable decisions which have by and large worked out. Assembled one of the best front sevens in the game.
HC Ron Rivera: 47-32-1 in five seasons with three-straight playoff appearances. 19-1 in his last 20 regular season games.
OC Mike Shula: Finished 11th in total offense and 1st in points scored. Offense has improved in each of his three seasons running the show.
DC Sean McDermott: Finished 6th in total defense and 6th in points allowed. Top 10 in total defense each of the last four seasons.
There was some thought the team could move on from GM Thomas Dimitroff, but Arthur Blank gave him a vote of confidence shortly after the season. More of a committee member than general manager at this point, Dimitroff will continue to work with coach Dan Quinn and assistant GM Scott Pioli to make personnel decisions.
GM Thomas Dimitroff: Held the position since 2008. Some of his duties given to assistant GM Scott Pioli last season.
HC Dan Quinn: 8-8 in his first season as head coach. Team collapsed after a 6-1 start.
OC Kyle Shanahan: Finished 7th in total offense and 21st in points scored in his first year with the Falcons. Teams have finished in the top ten of total offense three of last four seasons.
DC Richard Smith: Finished 16th in total defense and 14th in points allowed in his first season with Falcons. After five combined seasons as a coordinator, Smith has not had a defense finish inside the top twelve in scoring or total defense.
There were rumblings about coach Jason Garrett’s job security, but he was never really in danger. Dallas will likely lose DBs coach Jerome Henderson, who interviewed for the Browns head-coaching vacancy and is rumored to be joining Adam Gase in Miami.
GM Jerry Jones: De facto general manager since 1989. Has ceded some duties to Stephen Jones and Will McClay the last several seasons.
HC Jason Garrett: 45-43 in five and a half seasons with one playoff appearance. Served as the offensive coordinator and assistant head coach from 2008-10.
OC Scott Linehan: Finished 22nd in total offense and 31st in points scored. Was without Tony Romo for all but four games.
DC Rod Marinelli: Finished 17th in total defense and 16th in points allowed. Finished dead last in takeaways in 2015 after finishing 2nd last season.
Green Bay Packers
Tom Clements had play-calling duties stripped in December, but it is unlikely there are any significant changes.
GM Ted Thompson: Held the position since 2005. One of the most respected general managers in the game.
HC Mike McCarthy: 104-55-1 in with one Super Bowl championship in 10 seasons. Only one losing season over that stretch with eight playoff appearances.
OC Tom Clements: Edgar Bennett has the title, but Clements fills the role. Clements had play-calling duties stripped in December. Finished 23rd in total offense and 15th in points scored.
DC Dom Capers: Finished 15th in total defense and 12th in points allowed. Has held the position since 2009.
An organization on the rise, it would be surprising if any major changes took place. The Vikings did replace Jeff Davidson with ex-Dolphins coach Tony Sparano as offensive line coach.
GM Rick Spielman: Held the position since 2006. Has rebuilt the defense by drafting Harrison Smith, Xavier Rhodes, Sharrif Floyd, Anthony Barr and Eric Kendricks since 2012.
HC Mike Zimmer: 18-14 with one playoff appearance in two seasons. 14 years of coordinator experience.
OC Norv Turner: Finished 29th in total offense and 16th in points scored. 25 years of coordinator and head coach experience.
DC George Edwards: Finished 14th in total defense and 5th in points allowed. Top 12 in points allowed each of his first two years in Minnesota.
The coaching staff has been consistently raided in previous seasons, but there have not been any rumors connecting coordinators to moves. OC Darrell Bevell has interviewed for head jobs in the past. Co-director of player personnel Trent Kirchner could land a GM job.
GM John Schneider: Held the position since 2010. Shares responsibilities with Pete Carroll.
HC Pete Carroll: 60-36 with one Super Bowl championship in six seasons. Has seven playoff wins and counting over that span.
OC Darrell Bevell: Finished 4th in total offense and 4th in points scored. Has received head-coaching interest in the past. Russell Willson has increased his yardage total in each of his first four seasons.
DC Kris Richard: Finished 2nd in total defense and 1st in points allowed in his first season as coordinator. Has been an assistant in Seattle since 2010.
No big changes are expected after the team’s first playoff appearance since 2012. Ex-Colts DC Greg Manusky was hired as the OLBs coach.
GM Scot McCloughan: Held the position one season. Deserves much of the credit for the 49ers’ talent pool during the NFC Championship years.
HC Jay Gruden: 13-19 with one playoff appearance in two seasons. Made the controversial but correct decision to go with Kirk Cousins at starting quarterback before the season.
OC Sean McVay: Finished 17th in total yards and 10th in points scored.
DC Joe Barry: Finished 28th in total defense and 17th in points allowed in his first year as coordinator.
