PITTSBURGH — Ben Roethlisberger is well versed in the drill. When things go well, the Pittsburgh Steelers quarterback is quick to deflect praise elsewhere.

And when they don’t, he’s just as quick to shoulder the responsibility regardless of how many yards he passes for or touchdowns he throws.

“We take these losses on us as an offense, and me as a leader of the offense, I take it on myself that we haven’t done enough to score enough points to win football games,” Roethlisberger said Wednesday. “So, offensively we need to be better and we will be better.”

Thing is, on paper Pittsburgh’s offense looks fine. The Steelers (1-2-1) are a respectable sixth in total yards and 10th in points heading into Sunday’s visit from Atlanta (1-3).

The problem is the success has come in fits and spurts. Consistency has been elusive. For every 21-point flurry — such as the one against Kansas City in Week 2 that helped them escape from an early hole — there have been large swathes of meh.

And while coach Mike Tomlin is frustrated by his team’s slow starts — the Steelers have been outscored 42-6 in the first quarter — the finishes haven’t been great either. Pittsburgh has just one fourth-quarter touchdown through four games, a 3-yard dive by Roethlisberger in the waning moments against the Chiefs.

The Steelers often look dynamic and vulnerable in the same half, a sporadic juggernaut that doesn’t exactly have Atlanta Falcons defensive end Takk McKinley overly concerned. The brash second-year player is eager to get a look at Roethlisberger, Antonio Brown and the rest of a team coming off its worst September in five years.
