Wrap-up: Steelers 19, Titans 11

Here are some thoughts on the Pittsburgh Steelers' victory over the Tennessee Titans:

What it means: The Steelers are off to a tremendous and unexpected 2-0 start without quarterback Ben Roethlisberger, who is suspended four games for violating the NFL's personal conduct policy. Pittsburgh has found its formula minus "Big Ben" and is successfully sticking to it. With the Cincinnati Bengals (1-1) beating the Baltimore Ravens (1-1) Sunday, the Steelers are currently in first place in the AFC North.

What I liked: It doesn't matter who's playing quarterback if the Steelers' defense continues to play lights out the way that it has. Pittsburgh went on the road and dominated a Tennessee offense that scored 38 points the previous week. The Steelers forced an amazing seven turnovers (four fumbles, three interceptions). The return of safety Troy Polamalu has been huge. He has an interception in each of the first two games.

What I didn't like: The knee injury to starting quarterback Dennis Dixon is the worst thing to happen Sunday. He was carted off the field, which isn't a good sign. Backup Charlie Batch only threw for 25 yards in place of Dixon, but the defense was so dominant that lack of quarterback production didn't matter. Byron Leftwich will be re-signed Monday. With injuries and Roethlisberger's suspension, the Steelers have plenty of quarterback questions heading into Week 3.

What's next: The Steelers will face the Tampa Bay Buccaneers (2-0) in a battle of surprising undefeated teams. Pittsburgh has two more games without Roethlisberger and has positioned itself to have a very good chance to enter its bye week with a winning record.
