Answer based on context:

After a great season for the Miami Dolphins in 2008, the Dolphins went to the Georgia Dome to take on 2008 playoff contenders, the Atlanta Falcons.After a scoreless first quarter, the Falcons got on the board with a 1-yard touchdown pass from Matt Ryan to fullback Ovie Mughelli in the second quarter. They also got a 36-yard field goal by kicker Jason Elam to make the score 10-0 at halftime. In the third quarter, Mike Peterson intercepted a Chad Pennington pass, which set up a 20-yard touchdown pass to tight end Tony Gonzalez and a 50-yard field goal by Jason Elam to make the score 19-0. Chad Pennington then hit a 9-yard touchdown pass to Ricky Williams. The Falcons won the game 19-7 as the Dolphins started their season 0-1. In 2008, no other team turned the ball over less than the Dolphins with only 13 turnovers, but in Week 1 Miami's offense had 4 turnovers, without having a single turnover on defense.
