Problem:Passage: Coming off their dominating Monday Night performance against the Ravens, the Steelers stayed at home for Round 2 of the 2007 Rust Belt series against the Cleveland Browns. In the first quarter, Pittsburgh trailed early as Browns QB Derek Anderson completed a 4-yard TD pass to TE Kellen Winslow. The Steelers managed to get a 28-yard field goal from kicker Jeff Reed. In the second quarter, Cleveland increased its lead with Anderson completing a 2-yard TD pass to FB Lawrence Vickers, while Pittsburgh only managed to have Reed kick a 35-yard field goal. Afterwards, the Browns continued their fast start with Anderson completing a 16-yard TD pass to WR Braylon Edwards. The Steelers drove into the red zone once again but settled for a 30-yard field goal from Reed. Both teams scored thrice in the first half; Cleveland led 21-9. In the third quarter, Pittsburgh began to come back as QB Ben Roethlisberger completed a 12-yard TD pass to WR Hines Ward for the only score of the period. In the fourth quarter, the Steelers took the lead with Roethlisberger getting a career-best 30-yard TD run. Cleveland WR/KR Joshua Cribbs returned the ensuing kickoff 100yards for a touchdown. Pittsburgh on their next drive retook the lead with Roethlisberger completing a 2-yard TD pass to TE Heath Miller. The Browns tried to force overtime with a late field goal, but kicker Phil Dawson's 53-yard attempt came up short with 6seconds left. With their ninth straight win over Cleveland, the Steelers improved to 7-2 increasing the all-time series to 57-55.
