The 2006 Houston Texans season, the first under head coach Gary Kubiak, showed significant growth as the team improved to a 6-10 record, a four-game increase from the previous year. The season was highlighted by the sensational debut of DeMeco Ryans, who earned AP Defensive Rookie of the Year honors, and a historic Week 16 victory over the eventual Super Bowl champion Indianapolis Colts. The first overall pick in the 2006 NFL Draft, Mario Williams was a dominant defensive end for the Houston Texans who earned two Pro Bowl selections and recorded 53 sacks during his six seasons with the franchise.
