When asked in the wake of the Pittsburgh Steelers lopsided defeat on Sunday at the hands of the Cleveland Browns whether the scheme employed by the offense was hindering the team's ability to win games, quarterback Ben Roethlisberger pleaded ignorance.

"I don't know," said Roethlisberger. "We can all look at the film. Coaches will look at it. We tried to run it in the red zone and when we got down there, we just couldn't quite get it all the way in. We'll look at it and figure out what the execution, figure out what it is."

The Steelers lost 31-10 to the Browns and many are asking in the wake of this shellacking whether the gameplans of offensive coordinator Todd Haley are to blame.

Haley has been the offensive coordinator in 38 games since the "retirement" of Bruce Arians, much reviled in the same role in the previous five seasons. The Steelers are 19-19 in those 38.

In the 38 games before Arians departed, the Steelers were 27-11. In his five seasons with Tomlin, the Steelers were 55-25, winning 12 games three times.

Now? The offense is averaging a paltry one to two touchdowns per game and they're doing it against some of the league's worst defenses.

They managed only one touchdown against Cleveland and one the week prior against Jacksonville.

For his part, head coach Mike Tomlin is certain the scheme isn't to blame.

The culprit? Execution.

"I am sure of it," said Tomlin. "But we are not executing. We've got to look at all areas. We missed some throws. We had people in position to make plays who didn't. The bottom line is that we came up short in that area and we can't."

Even if execution is to blame, that still falls on Haley's shoulders. It's his job to get the offense ready for work week in and week out. Their failures - whatever name you want to call them by - are his failures.

With a Pro Bowl quarterback in Ben Roethlisberger and a dynamic young running back in Le'Veon Bell, the Steelers offense should be much more productive than they've recently been.

The only question is - where does the fault for their anemic output truly lie?
