Rapid Reaction: Seahawks 23, Texans 20

HOUSTON -- A few thoughts on the Seattle Seahawks' 23-20 overtime victory against the Houston Texans at Reliant Stadium.

What it means: Even on a day when the Seahawks looked awful in many areas of the game, they still found a way to win, pulling off a stunning come-from-behind victory on the road. This game showed the Seahawks have some problem areas on the offensive line and can give up big yards on defense. But it was quarterback Russell Wilson's scrambling and running downfield that got Seattle back in the game in the fourth quarter. Then a Richard Sherman 58-yard interception return for a touchdown tied the game before a Steven Hauschka 45-yard field goal won it. This is the first time the Seahawks have ever won the first four games in a season.

Stock watch: An awful day for the Seattle offensive line, but no one should be surprised with three starters injured. Free safety Earl Thomas had an early interception off a tipped ball and Sherman tied it in the fourth quarter with the pick-six, but the Seahawks struggled on defense in the first half. It was a season-worst day for the defense early, but things changed in the second half and overtime when the Seahawks' defense looked like the No. 1 unit in the NFL.

First half woes: The Seahawks gave up 324 yards in the first half, including 226 yards passing. The Texans led 20-3 at the half after Houston receivers were wide open in the middle of the field against the highly acclaimed Seattle secondary. What happened?

Wilson a sitting duck all day: With three starters out on the offensive line, including Pro Bowlers Max Unger and Russell Okung, the backups up front were no match for defensive end J.J. Watt, linebacker Whitney Mercilus and the other Houston pass-rushers. Wilson was sacked five times and under pressure on almost every pass play, yet still managed to bring the Seahawks back in the fourth quarter and lead the team to victory.

What’s next: The Seahawks travel to face the Indianapolis Colts at Lucas Oil Stadium. It will be the second consecutive 10 a.m. PT start time for the Seahawks and the third of five 10 a.m. starts this season.
