While the Tampa Bay Buccaneers retained Dirk Koetter after last year's 5-11 season, oddsmakers believe he will be the first head coach fired in 2018.
According to OddsShark, Koetter leads the way with plus-250 odds (a $100 bet would win $250), ahead of Cleveland Browns coach Hue Jackson and Vance Joseph of the Denver Broncos.
Odds for Which Coach Will Be Fired First
Dirk Koetter (Tampa Bay Buccaneers): +250
Hue Jackson (Cleveland Browns): +350
Vance Joseph (Denver Broncos): +650
Adam Gase (Miami Dolphins): +750
Marvin Lewis (Cincinnati Bengals): +1600
Todd Bowles (New York Jets): +1600
Bill O'Brien (Houston Texans): +2000
Jay Gruden (Washington Redskins): +2800
Frank Reich (Indianapolis Colts): +3300
Jason Garrett (Dallas Cowboys): +3300
John Harbaugh (Baltimore Ravens): +3300
Jon Gruden (Oakland Raiders): +3300
Matt Nagy (Chicago Bears): +3300
Mike Vrabel (Tennessee Titans): +3300
The top names on the list aren't too surprising considering their teams' lack of success in recent seasons.
Koetter raised the Bucs' hopes after a 9-7 campaign in his first year, but a turbulent offseason featuring quarterback Jameis Winston's three-game suspension has followed a disappointing 2017.
Considering the organization hasn't reached the playoffs in 10 seasons, another lost year could be enough for another change in Tampa Bay.
Meanwhile, Jackson is a top candidate after going just 1-31 in his first two seasons in Cleveland. While expectations are higher after some key additions in the offseason, including quarterback Tyrod Taylor and No. 1 overall pick Baker Mayfield, a few more weeks without winning could cause the franchise to move on.
Some first-year coaches are also potentially on the hot seat, including Frank Reich and Mike Vrabel. Oakland Raiders coach Jon Gruden remains relatively high considering he signed a 10-year deal worth about $100 million this offseason.
With the unpredictability of the regular season, however, there are a number of coaches who could be on the hot seat by December. Seven organizations made a swap at the position for 2018.
