The Texans started off the 2015 season with two wins and five losses pointing to another lost year. Their defense made a nice step forward leading to seven wins in their last nine games and a playoff berth. Bill O’Brien has done an excellent job in his two seasons as head coach (18-14) and he’ll return for a third season. Houston ranked third in the NFL in yards allowed while giving up 313 points (7th). Romeo Crennel will return for his third season as defensive coordinator. Romeo had a failing resume as a head coach (28-55) with eight years of experience as a defensive coordinator.
