The Houston Texans franchise only extends back to 2002, and in its brief time in the league, the team has had trouble breaking into the top tier of NFL teams, despite some recent success. As such, the list of Texans coaches is not long.
Four coaches have been given the reins to the Texans franchise, though Wade Phillips was only given the chance to finish out the 2013 season after Gary Kubiak's tenure ended uncermoniously. Kubiak was fired midseason after back-to-back playoff losses. Bill O'Brien then took over, and while he has led the Texans to the playoffs three times, there has yet to be a major breakout from the franchise.
