The AFC North side rushed for a total of just 32 yards in their season opener against the Tennessee Titans at the weekend.
The head coach told the team's website: "I think a consistent running game is really important, not only to be good offensively, but to strike a balance. We haven't been able to do that to this point. Obviously, we are working hard to do so.
"We got in some circumstances within the game, particularly as the game wore on, where we were down by two scores and we had to pick the pace of the offense up. Some of that requires non-verbal communications."
The Steelers play the Cincinnati Bengals next Monday.
