Entering the first day of the offseason for 18 teams, three head coaching jobs are open. The Tennessee Titans and New York Giants fired coaches during the season, with the Falcons making the first head coaching move of the offseason. There may be several more openings as teams evaluate their seasons this week.

Just nine months after signing a three-year contract extension, the Baltimore Ravens have fired head coach John Harbaugh.

Harbaugh led the Ravens for 18 years, with a Super Bowl championship.
