HOUSTON -- Houston's defense flattened Ryan Tannehill and the Miami Dolphins in minutes.
Arian Foster had two touchdown runs, Matt Schaub threw a TD pass to Andre Johnson, and Houston overwhelmed the rookie quarterback in the Texans' 30-10 win over Miami on Sunday.
Tannehill, the eighth overall pick in the draft, completed 20 of 36 passes for 219 yards in his NFL debut. But he threw three interceptions in a game-turning stretch late in the first half, and the Texans marched to an impressive opening win in what they believe can be a Super Bowl season.
"We were explosive as a team in that period of the second quarter," Texans coach Gary Kubiak said of his defense's six minutes of opportunism.
Defensive end J.J. Watt deflected two passes that resulted in interceptions and also had 1½ sacks. The 6-foot-5 Watt, Houston's first-round draft pick in 2011, missed most of training camp with a dislocated left elbow.
"I know I have long arms," Watt said. "You can't get a sack every play, so you might as well try to bat the ball."
Schaub threw for 266 yards in his first action since fracturing his right foot in Week 10 last year, and Johnson finished with 119 yards receiving. Schaub announced after the game that he had signed a four-year contract extension that will keep him here through the 2016 season.
"I'm excited for it to be done and over with so every ounce of focus and energy can be directed to this season," said Schaub, whose previous contract was due to expire after this season.
