Question: How many points were the Steelers leading by at halftime?

Input: The Indianapolis Colts began their 2011 season at Reliant Stadium against the Houston Texans. For the first time since the 1998 season, Peyton Manning was not under the helm at quarterback and it was recently acquired Kerry Collins that would take his position. The game started very well for the Colts, opening up with an interception by Melvin Bullitt that allowed the Colts to take control. However, a three and out from the offense quickly gave the Texans the ball to drive down and score a field goal and take a 3-0 lead. Collins and the Colts offense was out of sync for much of the first quarter, fumbling two snaps and giving Houston the great field position inside of the Indianapolis 40-yard line. After the first quarter, the Texans held a commanding 17-0 lead and were firing on all cylinders. The second quarter continued Houston's dominance, with all three teams of the Colts failing to stop or to execute against the Texans. At halftime, the Colts trailed Houston 34-0, the largest deficit in the entire 58-year history of the franchise. The second half saw little action with both teams taking shorter drives and in some senses, running down the clock. The Colts scored their first and the only points scored in the second half with a Reggie Wayne touchdown from Collins in the fourth quarter. The Colts went on to lose to the Texans 34-7, their second straight season starting 0-1.

In the fourth quarter, the Chargers tried to come back as kicker Nate Kaeding nailed a 36-yard field goal. Unfortunately, the Vikings sealed the win with Peterson getting a 46-yard TD run, along with RB Chester Taylor getting a 2-yard TD run. LaDainian Tomlinson, despite getting only 1 rushing touchdown, managed to surpass Jim Brown for most career rushing touchdowns with his 107th TD.
