LANDOVER, Md. -- Their quarterback threw for 497 yards. They overcame a 17-point third-quarter deficit. They've beaten Peyton Manning and Donovan McNabb back-to-back. They even won an overtime game for the first time.

Needless to say, these are not your older brother's Houston Texans.

Houston won a wild one Sunday, a game that produced nearly 1,000 yards of offense and wasn't done until Neil Rackers kicked a 35-yard field goal with 3:24 left in the extra period. The Texans knocked off the Washington Redskins 30-27 to move to 2-0 for the second time in the franchise's nine-year history, giving promise that this might be the year they finally make the playoffs.

"My thought coming into this week was that I knew that a lot of people was going to be questioning us, asking if we were for real," said Andre Johnson, who had 158 yards receiving and tied a career high with 12 catches despite leaving the game for part of the second half with a sprained right ankle. "I think we showed a little something today."

A week after Arian Foster rushed for a franchise-record 231 yards in an upset over the nemesis Indianapolis Colts, the Texans went back to the air. Matt Schaub completed 38 of 52 passes for 497 yards -- another franchise record -- with three touchdowns with one interception despite getting sacked five times.

Kevin Walter caught 11 passes for 144 yards. Foster had 69 yards on 19 carries and caught three passes for 69 yards. Mario Williams was the defensive star in a game without much defense, sacking McNabb three times.

Two of Schaub's completions stand out above the others. A fourth-and-10 heave turned into a touchdown when Johnson outjumped safety Reed Doughty in the end zone to snag a 34-yard touchdown pass that tied the game at 27 with 2:03 to play to regulation, Johnson's 601st career catch.

A similar throw led to Joel Dreessen's leaping, turnaround grab in overtime, a 28-yard pass to move the ball to the Washington 18 to set up Rackers' kick, giving the Texans their first overtime win in seven tries since entering the league in 2002.

"I'm just trying to give guys a chance to make a play," Schaub said. "The one to Andre was fourth down. He had two guys on him. I don't even know how he caught it. ... We got behind in a tough environment and we battled, and it just shows the resolve this team has."

McNabb was also cranking it out, hitting 28 of 38 passes for 426 yards with one touchdown for the Redskins, who are 1-1 under new coach Mike Shanahan. It was the first time both quarterbacks threw for more than 400 yards in an NFL game since Drew Bledsoe and Dan Marino put on a show when New England played Miami in September 1994, according to STATS.
