"You have to jump in, and you might get beat over the top for a 20- or 30-yard gain if he gets the ball down there. But if you make the play, you might get a pick-6 and change the game for your team," said Sherman.
On 3rd and 4, Texans QB Matt Schaub threw toward Owen Daniels and Sherman stepped in front for the interception and touchdown as he lost his shoe in the process.
Down 3-0, the Texans offense looked brilliant when Schaub launched a great pass to Garrett Graham for the 31 yard touchdown and the 7-3 lead in the second quarter.
Texans added to the lead later on when Arian Foster ran in a 5 yard touchdown for the 14-3 score.
Seattle attempted to put more points on the board, however Marshawn Lynch fumbled which resulted in a Texans field goal by Randy Bullock that extended the lead 17-3.
Later Bullock would add another field goal before halftime that made it 20-3.
After a Steven Hauschka field goal in the third quarter, the Seahawks dominate the fourth quarter.
Lynch capped off a 98 yard drive with his three yard touchdown that brought them within a touchdown, 20-13.
In the overtime period the Seahawks caught a key break when Doug Baldwin caught a pass and was slammed to the ground WWE style by Kareem Jackson. That caused a 15 yard penalty and allowed Seattle within field goal range a few plays later.
Hauschka booted a field goal for the 23-20 win, with the leagues best defense that held the Texans scoreless in the second half.
"We were dominating the whole first half ... and the second half we just didn't finish the game. It's very, very frustrating," said an upset JJ Watt.
Matt Schaub threw his third consecutive pick six interception this season.
Russell Wilson finished with 123 yards and one touchdown, willing his team to victory.
"Russell's play was off the charts! I don't even know what his numbers were; it didn't matter. You had to watch the game to see the things he did to give us a chance," said Seattle coach Pete Carroll.
Schaub finished 31/49 with 355 yards, two touchdowns and two interceptions in the loss.
Brian Cushing went out in the third quarter with a concussion and did not return. He will undergo test this week according to the NFL concussion standard.
