– Down to a last chance, Andy Dalton showed why these Bengals are unbeaten through seven games.

Dalton passed for Cincinnati's only touchdown with 2 minutes, 57 seconds to go, and the Bengals picked off Ben Roethlisberger twice in the fourth quarter while rallying for a 16-10 victory over the Steelers on Sunday that gave them the best start in franchise history.

They're 7-0 and in command of the AFC North heading into the midpoint of the season.

"We're playing for something greater than being 7-0," said A.J. Green, whose TD catch was part of another big game against Pittsburgh. "We're trying to win a championship. We feel a game like this helps us build resiliency going into the postseason."

Cincinnati hasn't won a playoff game since the 1990 season, the sixth-longest streak of postseason futility in NFL history. The Bengals have lost in the first round each of the past four years, but this team senses it's different.

"I don't even know how to explain it," said Shawn Williams, whose interception set up the winning TD. "When there's a special moment in the game and a play has to be made, they made the play."

The defending AFC North champion Steelers (4-4) hoped Roethlisberger's return after missing four games because of a sprained knee would kick-start them. After leading most of the game, they fell apart in the closing minutes.

Williams' diving sideline interception at the Pittsburgh 45-yard line set up Dalton's 9-yard touchdown pass to Green, who had 11 catches for 118 yards. Dalton had been waiting for one last chance.

"I knew eventually we were going to score a touchdown, and we did," said Dalton, who was 23 of 38 for 231 yards with two interceptions and three sacks.
