At 3-0, Roethlisberger-less Steelers Sit atop Power Rankings

Heading in to week four, the Pittsburgh Steelers, playing with its fourth string quarterback Charlie Batch, are one of the three undefeated teams remaining. What may be even more surprising may be who they beat, and how they won.

It's clear that Pittsburgh's "Steel Curtain" defense of old is back in action with the return of safety Troy Polamalu lurking the defensive backfield. Dick LeBeau's defense is ranked No. 1 in scoring, with just 11 points per game allowed, and fourth in the league in sacks.

Two of the team's three games were against possible playoff contenders, Atlanta and Tennessee, and the third, Tampa Bay, has gotten off to a surprising 2-1 start. Just two touchdowns allowed on defense and a week three blowout against the Bucs is what has the nation convinced that Blitzburgh is back in 2010.

With one last game without the suspended Ben Roethlisberger under center (Sunday v.s. 2-1 Baltimore), the Steelers have a shot at starting the season with a 4-0 record. And with Baltimore running back Ray Rice banged up, Pittsburgh shouldn't have much trouble keeping the Ravens one dimensional, meaning another victory in the 'W' column.
