LATROBE, Pa. - The Steelers' offense ultimately accomplished its goal in the first two-minute drill of training camp, but the drive was just as definable by plays that weren't made.

The offense was given the ball 65 yards from the end zone with 1:53 to play, in need of a touchdown and with one timeout available.

And the march ended on a 13-yard touchdown pass from quarterback Ben Roethlisberger to wide receiver Antonio Brown on first-and-10 from the 13-yard line with 20 seconds remaining.

But much of what happened in between wasn't what the Steelers were after on either side of the ball.

Cornerback Antwon Blake batted down a pass intended for wide receiver Darrius Heyward-Bey, but head coach Mike Tomlin scolded Blake for not using two hands and instead coming down with an interception.

Bey couldn't come up with a deep ball down the sideline that would have produced a big gainer if not a touchdown.

Roethlisberger couldn't connect with uncovered wide receiver C.J. Goodwin on a deep ball down the middle (Goodwin caught the ball but was unable to get his feet down in the back of the end zone).

And safety Robert Golden suffered what Tomlin characterized as a "significant injury" on a 12-yard completion to Brown on fourth-and-10, a play that might have resulted in a sack had the defense been interested in tackling Roethlisberger.

"It's the structure of the drill (that's important) and that's something we explain to them all the time," Tomlin said. "There might be instances where there's pressure on the quarterback that could be viewed as a sack but we're going to let the play develop and finish down the field.

"It's not perfect, it's not football but I structure it so that we work our way down the field and work our way through the scenarios involved in the situation. There are no true winners and no true losers because I doctor the drill to make sure we get what we're looking for."

Roethlisberger was 6-for-12 passing for 65 yards and a touchdown in the drill, repeatedly stepping up in reaction to pressure before firing.

The second-team series ended on an interception of quarterback Landry Jones by cornerback Kevin Fogg.

"With that second group we had a lot of young guys plugged in," offensive coordinator Todd Haley said. "We had (quarterback/wide receiver) Tyler Murphy playing slot (receiver) and that's gonna be a bear for us."

As for Roethlisberger, "He excels in that area," Haley said. "He has a great command of everything that's going on. He's calling the plays. He's calling the formations, moving people around, understands where the weaknesses are and does a great job in it generally.

"It's an area we want to be real strong in. We were real good last year for the most part but we're not settling for that. That's our first day of it. We have a chance now to coach them up and get another shot at it before the game."

The Steelers open the preseason on Sunday night in Canton, Ohio against the Minnesota Vikings.
