Pittsburgh has the No. 1 defense in the NFL, yet its offense ranks way down there at No. 26 overall, and that's not likely to improve when they but heads against the Ravens and their No. 2-ranked defense in Baltimore on Sunday.

The Steelers defense scored as many touchdowns as its offense on Sunday with cornerback Deshea Townsend returning a 25-yard interception for a touchdown in the final two minutes to beat the Dallas Cowboys, 20-13.

"Our defense is the best in the world for a reason," quarterback Ben Roethlisberger said. "They kept us in the game and gave us an opportunity to come back late and put some points on the board, and eventually tie the game. That's what this is about. That's what the team is about. We're the Pittsburgh Steelers offense, defense, and special teams got it done."

The Steelers forced five turnovers in that game, four on defense and one on special teams, constantly turning the ball over to its offense in good field position. Yet, they still trailed 13-3 before finally scoring 10 points to tie it with 2:04 left, setting up Townsend's TD return.

Pittsburgh has a Super Bowl contending team, but it's hard to believe the Steelers will make it that far with that kind of play from its offense. The biggest problem is its No. 23-ranked running game that has dropped off the edge of the traditional map they like to use. It would be their second-lowest ranking on the ground since the NFL merger in 1970.

"We have to get better," coach Mike Tomlin said.
