2018 Tennessee Titans season

The 2018 Tennessee Titans season was the franchise's 48th season in the National Football League and their 59th overall. It also marks the franchise's 22nd season in the state of Tennessee, their first under head coach Mike Vrabel, and the first with new uniforms and blue helmets, as they have worn white helmets since the club was based in Houston, Texas. This season marks the third straight in which the Titans have finished 9–7. The Titans failed to qualify for the postseason after losing a Week 17 win-and-in contest against their division rival Indianapolis Colts.

One highlight from this season includes the Titans beating the New England Patriots for the first time since 2002, a season after the Patriots won their first Super Bowl title, also the second of three times Bill Belichick's Patriots had missed the playoffs.

Coaching changes
On January 15, 2018, the Titans and former head coach Mike Mularkey agreed to part ways, ending his three year tenure as head coach with a record of 20-21. Five days later, the Titans named former Houston Texans defensive coordinator Mike Vrabel as the new head coach. Vrabel became the 18th head coach in franchise history. Two weeks later of January 30, the Titans announce the hiring of the new offensive coordinator, Matt LaFleur. LaFleur was with the Los Angeles Rams in 2017, and was credited for the development of Jared Goff. On the same day, the Titans hired their new defensive coordinator Dean Pees. The next day, the Titans announced several additions to the coaching staff, including quarterback coach Pat O'Hara, secondary coach Kerry Coombs, outside linebackers coach Shane Bowen, inside linebackers coach Tyrone McKenzie, and wide receivers coach Rob Moore.

Offseason acquisitions
The Titans signed two former New England Patriots players. Running back Dion Lewis and Cornerback Malcolm Butler. The two reunited with current cornerback Logan Ryan, who also played for the Patriots, in which their last season in New England together was capped off with a Super Bowl comeback win.
