Those tricky Ravens?

Posted by ESPN.com's James Walker

BALTIMORE, Md. -- Where was this super-charged offense in the preseason?

The Ravens ran a tricky, double-reverse to receiver Mark Clayton, who ran for a 42-yard touchdown to take an early 7-0 lead, which is where it stands at the end of the first quarter.

Baltimore receiver Derrick Mason received an end around from rookie quarterback Joe Flacco, who threw a key block after Clayton received another end-around from Mason. The home crowd went into a frenzy after a solid call by offensive coordinator Cam Cameron.

The Ravens caught the Bengals by surprise after playing mostly vanilla on offense in the preseason. It was the first touchdown drive in the career of Flacco and first-year coach John Harbaugh.
