Pittsburgh's offense struggling early

Posted by ESPN.com’s James Walker

PITTSBURGH -- The Steelers offense is sputtering out the gates.

Big time.

Pittsburgh was held scoreless in the first quarter, and it wasn’t pretty. Quarterback Ben Roethlisberger telegraphed an interception. The running game has been non-existent so far, and the offensive line has given up two sacks.

Give credit to Tennessee’s defense, which is one of the NFL’s best. The unit looks a step ahead of Pittsburgh's offense in the early going.

So far, it looks like it will be a defensive struggle.
