BALTIMORE -- Wide receiver Antonio Brown knows what the Pittsburgh Steelers must do to combat the constant double-teams he is facing.

"Others have to step up," said Brown from his locker after Sunday's 21-14 loss to the Baltimore Ravens.

Brown didn't say this as an indictment on his teammates, but matter-of-factly when discussing the attention he gets from defenders. Brown said the Ravens sometimes shaded a third defender, a linebacker, on him during routes. This setup begs other playmakers to win one-on-ones.

Brown finished the game with 7 catches for 85 yards and 1 touchdown, but much of that production came in the fourth quarter as the Steelers (4-4) battled back from a 21-0 deficit.

The Steelers' offense has struggled in three straight road games, leaving an uphill climb to the playoffs. Pittsburgh had 69 yards of total offense through the first three quarters. With 55 catches for 677 yards and 6 touchdowns, Brown is having a fine season but not producing at the otherworldly level of the past two years.

After Brown said the Ravens "used a lot of guys to take me away," he was asked what's required of the Steelers' other receivers when that happens.

"They need to find a way to step in, step up and make plays," Brown said. "It's been about eight weeks so far, and that's what we've been seeing -- double coverage. Today it was triple coverage with a linebacker coming over, and we just have to find ways to win. Other guys have to step up. It just shows that people got respect for me, but we have to find a way to win no matter what they do. It's all about what we do."

Steelers quarterback Ben Roethlisberger took ownership of the loss Sunday, saying after the game, "I didn't make plays, I didn't convert third downs."

But the Steelers have struggled to find a reliable No. 2 receiver behind Brown, who benefited from Martavis Bryant's playmaking last year. Bryant is suspended, and though Sammie Coates produced 421 yards through the first five games, he has been quiet in his past three outings while coming back from a finger injury.

Eli Rogers led the team with 103 receiving yards Sunday, most of which came late in the game, but he didn't play the previous game against the New England Patriots because of what he called a "coach's decision."

Running back Le'Veon Bell is a talented pass-catcher, but he can only do so much from the backfield.

"We can't make any excuses," said Brown about being 4-4. "We've got to find a way to continue to get better, and we get a fresh start next week. We've got to get things on the right side."
