PITTSBURGH — The Pittsburgh Steelers spent training camp talking about taking the next step after a crushing Super Bowl loss to Green Bay.

It took the Baltimore Ravens all of a half to give the defending AFC champions a sobering reality check.

The Ravens dominated Pittsburgh in every phase of a 35-7 win in the season opener on Sunday, leaving the Steelers stunned after turning the ball over seven times and allowing their division rivals to have their way on both sides of the ball.

Wide receiver Antonio Brown said Monday the Steelers were "humbled" by the Ravens. The offense, considered the most potent in quarterback Ben Roethlisberger's eight years on the job, turned it over seven times.

Brown says there's plenty to work on before facing Seattle next Sunday.
