Mike Tomlin disappointed in offense

Pittsburgh Steelers coach Mike Tomlin on Tuesday pinned the blame on his club's unproductive offense as the primary reason for an 0-2 start.

"The most significant reason is we're 0-2 is we're not scoring enough points," said Tomlin, whose team has scored two touchdowns in the first two games. "Nineteen points in two football games is not going to win a lot of football in this league. If you would have told me we'd score 19 points through the first two ball games I would have told you we'd have an opportunity to 0-2. We understand that and we are working hard to rectify that."

The Steelers, trying to avoid their first 0-3 start since 2000 when they host the Chicago Bears on Sunday night, may get some reinforcements on the offensive side of the ball.

Tight end Heath Miller (knee) and rookie running back Le'Veon Bell (foot), who have not played this season, will ramp up their activity in practice and be evaluated later this week. Bell could boost a running game that has accounted for just 75 yards rushing in two games. Pittsburgh ran for 44 yards in Monday night's 20-10 loss at Cincinnati.

In addition to wanting more points, Tomlin also is looking for better offensive line play out of tackles Marcus Gilbert and Mike Adams, saying, "They need improvement in terms of their quality of play like a lot of us," he said.
