The 2015 Houston Texans season was the football equivalent of a car that stalls three times in the driveway before somehow winning a drag race. Coming off a 9-7 campaign, Bill O’Brien’s squad entered the year with mediocrity written all over them, especially after an uninspiring offseason defined by signing aging run-stuffer Vince Wilfork and journeyman quarterback Brian Hoyer. By late October, the Texans looked completely dead and buried at 2-5 after a humiliating 44-26 blowout loss against Miami. Yet, playing in the laughably bad AFC South, Houston staged a remarkable second-half turnaround to finish 9-7, capitalizing on a weak division to capture the AFC South crown and sneak into the postseason.

Offensively, the Texans were a complete circus under center, cycling through four different starting quarterbacks due to injuries and underperformance. Hoyer won the musical chairs game enough to log nine starts, throwing for 2,606 yards and 19 touchdowns against seven interceptions, while Ryan Mallett, T.J. Yates, and Brandon Weeden all took their turns starting. The ground game completely lost its identity after star running back Arian Foster tore his Achilles just four games into his season, leaving Alfred Blue to trudge his way to a team-high 698 rushing yards at a sluggish 3.8 yards per carry. Despite finishing 21st in scoring offense with 339 points (21.2 ppg), the unit was held together by the sheer brilliance of receiver DeAndre Hopkins, who put up a historic 111-catch, 1,521-yard, 11-touchdown season despite catching balls from a rotation of backup-level quarterbacks.

While the offense scrambled for identity, the defense carried the entire franchise on its back, finishing third in the NFL in total yards allowed and seventh in scoring defense by limiting opponents to 313 points (19.6 ppg). The catalyst was defensive end J.J. Watt, who put together another legendary campaign, terrorizing opposing blockers to the tune of 17.5 sacks, 29 tackles for loss, and a staggering 50 quarterback hits. Under defensive coordinator Romeo Crennel, the pass rush became a nightmare as linebacker Whitney Mercilus enjoyed a breakout year with 12.0 sacks of his own, while rookie inside linebacker Benardrick McKinney alongside Brian Cushing solidified the middle of the field. In the secondary, veteran cornerback Johnathan Joseph defended 22 passes, anchoring a coverage unit that choked out opposing passing games down the stretch.

Looking back at the schedule, the turning point of the entire season happened on a Monday night in Week 10 against the previously undefeated Cincinnati Bengals. Trailing in the second half, Yates came off the bench to throw a game-winning touchdown pass to Hopkins, sparking an incredible four-game winning streak where the defense surrendered a combined total of just 35 points against Cincinnati, Tennessee, the Jets and Saints. A crucial 16-10 victory over the Indianapolis Colts in Week 15 almost clinched the division providing the spark needed for Houston to close out the regular season with three consecutive wins over divisional rivals, completely erasing the memory of their dismal 1-4 start to the year.

The magical regular-season run evaporated into thin air during the Wild Card round against the Kansas City Chiefs. Houston was thoroughly humiliated at NRG Stadium, turning the ball over five times - including a career-worst four interceptions and one fumble from Hoyer - in a soul-crushing 30-0 shutout loss. Despite the ugly postseason exit, the 2015 Texans carved out a legacy of elite defensive football overcoming quarterback instability. Watt rightfully took home his third NFL Defensive Player of the Year award, joining Lawrence Taylor as the only three-time winners in league history, while long snapper Jon Weeks earned a Pro Bowl nod along with Hopkins to cap off a truly bizarre division-championship season.
