Steelers pulling away?

Posted by ESPN.com's James Walker

PITTSBURGH--The Steelers may have figured out the defense of the San Diego Chargers.

After sputtering for a majority of the first half, Pittsburgh has scored touchdowns on back-to-back drives to take a 21-10 lead. Coming off a recent concussion, Steelers quarterback Ben Roethlisberger is looking solid and connected with tight end Heath Miller for an 8-yard score to open the third quarter.

Pittsburgh's last two scoring drives have been for 66 and 77 yards. Roethlisberger has completed 13 of his first 19 attempts against San Diego and tailback Willie Parker has been a solid compliment on the ground with 75 rushing yards and a touchdown midway through the third quarter.
