Head Coach Jim Mora era began his coaching debut for the Seahawks with a game at home against division rival St. Louis Rams. Quarterback Matt Hasselbeck and the offense struggled early, turning over the ball three times (two interceptions and one fumble) on the first quarter alone. After Rams kicker Olindo Mare missed a 37-yard field goal for the lead, Hasselbeck led the Seahawks to their first score of the game after he connected with tight end John Carlson for a touchdown. With the second quarter coming to a close, St. Louis returned a blocked field goal for a touchdown, only to have it overruled by a penalty. This gave another chance for the Seahawks to score, as Hasselbeck threw his second touchdown of the game to Nate Burleson to put the Seahawks up 14-0 by halftime. When the third quarter started, the Seahawks looked to increase its lead to win the game. Hasselbeck would lead the Seahawks to a 99-yard drive, capping it off 33-yard touchdown pass to Carlson. Julius Jones would seal the win with a 62-yard touchdown (and rushing 119 in total) run to put Seattle up by 28. The Seahawks defense would shutout the Rams, as they totaled only 247 total yards on offense and forcing two fumbles and three sacks. Seattle moved to 1-0 to start off the season, and beat the Rams for the ninth straight time.. In which quarter did the Seahawks turn over the ball the most?
