As the 2021-22 NFL season ends, familiar faces will be coaching on different sidelines next season as several NFL teams go on a hiring spree.

The head coaching carousel didn't take off as fast as it typically does, with NFL Network's Judy Battista pointing out that the first hire didn't occur until 18 days after the regular season ended.

Nine teams announced they were searching for a new head coach, which is two more than last year, ESPN reported.

Three of the teams, the Minnesota Vikings, Houston Texans, and New Orleans Saints, have yet to fill their vacancies.

Below you'll find a list of all the teams that have hired new head coaches:

Chicago Bears - After going 6-11 this season, the Bears fired head coach Matt Nagy. They became the second team to choose a new head coach when they hired Indianapolis Colts defensive coordinator Matt Eberflus on Jan. 27. The 51-year-old has 13 years of NFL coaching experience, having spent time in Cleveland and Dallas. This will be his first-ever head coaching gig.

Denver Broncos - The Broncos were the first team to make a splash when they announced they'd hired Green Bay Packers offensive coordinator Nathaniel Hackett. On Jan. 27, the 42-year-old became its 18th head coach, its fourth head coach in seven years. The team has struggled at the quarterback position, with the team having 11 different starters since 2016, KMGH's Troy Renck reported.

Houston Texans - The team fired David Culley after just one season in which the Texans went 4-13, ESPN reported. According to NFL Network's Ian Rapoport and Fox Sports' Jay Glazer, the team is set to hire former Bears head coach Lovie Smith.

Jacksonville Jaguars - In December, Urban Meyer was fired before finishing his first season as an NFL head coach. The franchise is looking to the future because the fifth team announced a new head coach when they added former Philadelphia Eagles coach Doug Pederson on Feb. 3. During his time with the Eagles, Pederson led the team to a Super Bowl LII victory.

Las Vegas Raiders - On Oct. 11, Jon Gruden resigned as head coach midway through the season after a report published by The New York Times stated that Gruden had made homophobic and misogynistic comments in the past. Under interim head coach Rich Bisaccia, the team clinched their first playoff berth since 2016.

On Jan. 31, the team named New England Patriots offensive coordinator Josh McDaniels its next head coach. This isn't McDaniels' first head coaching job. He served as the Broncos head coach from 2009-10.

Miami Dolphins - In January, the team fired head coach Brian Flores after he led the Dolphins to a 24-25 record over three years. On Feb. 1, Flores filed a class-action lawsuit against the league alleging racist hiring.

As the team looks to the future, they hired San Francisco 49ers offensive coordinator Mike McDaniel. McDaniel, who identifies as multiracial, is the first minority head coach hire in the 2022 cycle, the Washington Post reported.

Minnesota Vikings - The Vikings fired head coach Mike Zimmer on Jan. 10 and are expected to name Los Angeles Rams offensive coordinator Kevin O'Connell its next head coach, according to CBS Sports and Sports Illustrated.

New York Giants - The Giants became the third team to announce they've hired a new head coach when they picked Buffalo Bills offensive coordinator Brian Daboll. The 46-year-old takes over from Joe Judge, who was fired on Jan. 11 after two seasons. This will be his first head coaching job, but he has 20 years of NFL coaching experience, including stops in Cleveland, New England, Miami, and Kansas City.

New Orleans Saints - After spending 15 seasons with the team and leading them to a Super Bowl championship in 2010, head coach Sean Payton announced on Jan. 25 that he was stepping down as head coach. They have yet to name a new head coach.

Doug Pederson is out as head coach of the Philadelphia Eagles three years after guiding them to their first-ever Super Bowl title.

Eagles Chairman and CEO Jeffrey Lurie made the announcement Monday on Twitter.

"I have spent the last few weeks evaluating everything from this past year and looking ahead. We are all very disappointed with the way our season went and eager to turn things around, not just for next season but also for the future of the franchise," Lurie said in a statement. "Coach Pederson and I had the opportunity to sit down and discuss what that collective vision would look like moving forward. After taking some time to reflect on these conversations, I believe it is in both of our best interests to part ways."

The Eagles went 4-11-1 in 2020 and were 42-37-1 under Pederson during his five-year tenure as head coach. Pederson led the team to two division titles and three playoff appearances.

According to The Associated Press, Pederson and general manager Howie Roseman weren’t on the same page regarding many personnel moves, which ultimately led Lurie to choose his GM over Pederson.

“Although I am disappointed that this chapter of my career has come to an end, I am extremely proud of what we accomplished together,” Pederson said in a statement.

The New York Times reported that Pederson took a lot of heat from fans and players when he decided to bench rookie starter Jalen Hurts and play Nate Sudfeld in the fourth quarter of a Week 17 game against Washington, which they lost 20-14.

In his second season as head coach, Pederson's Eagles defeated Tom Brady and the New England Patriots in the Super Bowl. The team was led by backup quarterback Nick Foles who filled in after starting quarterback Carson Wentz was injured.

Wentz struggled in 2020, throwing only 16 touchdowns and 15 interceptions before being benched for Hurts. According to an ESPN report on Jan. 3, Wentz's relationship with Pederson was "fractured beyond repair."
