(2012 Miami Dolphins season)The Houston Texans began their 10th anniversary campaign with lofty expectations, with many columnists picking them to represent the AFC in the Super Bowl.  Despite the lofty expectations, the Texans began the season rather flatly, only managing a field goal on offense against a younger, more inexperienced Dolphins team.  Miami played the Texans tough throughout the first half, thanks in part to Reggie Bush's contributions on the ground.  However, the game took a stunning turn after the two-minute warning of the first half as the Texans forced three Dolphin turnovers, and quickly converted them into touchdowns to stretch the lead to 24-3 before halftime.  The Texans continued to ride their defense to a season opening 30-10 win over Miami.  Houston improved to 7-0 all-time against the Miami Dolphins as they started their season 1-0.
