Seven NFL head-coaching jobs opened up last year, and the 2018 cycle started early, as the Browns dumped Hue Jackson after their Week 8 loss to the Steelers.
What's next in the NFL coaching carousel? Here's everything you need to know about all the movement through hiring-and-firing season.

The Browns fired Hue Jackson (and offensive coordinator Todd Haley) in late October after a 2-5-1 start. Jackson finished his tenure in Cleveland with a 3-36-1 record. The Browns had the No. 1 overall draft pick the past two seasons, and they could be headed toward another top-five pick next year.
Teams that could make a coaching move
Todd Bowles entered the year 10-22 in his first two seasons as Jets coach, though he received a two-year contract extension at the end of the 2017 season. Will he get to see out that contract while the Jets rebuild?
Baltimore's downward spiral this season comes nine months after owner Steve Bisciotti acknowledged he considered firing John Harbaugh after last season. The Ravens are one of eight teams that haven't made the playoffs over the past three seasons, and they haven't won the AFC North since 2012.
Jason Garrett has only one playoff win in nine seasons as coach of the Cowboys, and Dallas has disappointed in 2018. He already decided to fire his offensive line coach in the middle of the season. Is it playoffs or bust to keep his job?
The Bucs promoted Dirk Koetter to coach after the 2015 season, and he went 14-18 in his first two years. He needs to win quickly. "It's his third year. He's got to prove that he should continue to coach," right tackle Demar Dotson said in October. "I love Dirk ... but if we don't win for Dirk, he'll probably be without a job."
Vance Joseph's first season in charge of the Broncos included an eight-game losing streak but ended with a show of faith from general manager John Elway after a 5-11 finish. In Year 2, though, Joseph needs his team to show improvement.
