PITTSBURGH -- The Steelers gain more appreciation for defensive end Aaron Smith's play whenever he misses a game because of injury.
Smith is out indefinitely after needing surgery to repair a torn triceps tendon in his left arm. Such injuries typically are season-ending, but the Steelers (5-1) plan to wait and see how quickly Smith recovers before deciding whether or not to place him on injured reserve.
Not only is the 6-foot-5, 298-pound Smith difficult to run against, the push he creates in pass-rushing situations -- even while regularly being double-teamed by 300-pound linemen -- opens up room for Harrison and LaMarr Woodley to get to the quarterback.
What worries the Steelers is this is Smith's third significant injury in the last four seasons. The 34-year-old missed the final 11 games of last season with a torn right rotator cuff, and the Steelers lost five of those. He also sat out the final four games in 2007, including a playoff game, and the Steelers lost all but one.
Statistics also show how valuable Smith is. Last season, the Steelers were allowing an average of 71 rushing yards per game until Smith was hurt. After that, the average climbed to nearly 100 yards per game, even as opponents also threw with more success against a defense that repeatedly failed to hold leads in the fourth quarter.
Tomlin speaks his mind
That's why the Steelers are willing to keep a roster spot open, even if it turns out an injury that occurred during the third quarter of a 23-22 victory at Miami on Sunday sidelines Smith for the rest of the season.
"You know the philosophy that we buy into, as far as the standard being the standard, and what we mean by that is those who step in have to play winning football," Tomlin said. "There are no excuses. Do I expect the guys that take his place to play like Aaron? Or to make similar plays? Maybe not, but they'd better be above the line."
Hood, the Steelers' first-round draft pick in 2009, had a strong training camp that hasn't carried over into the season.
"He's got a big-time opportunity to work on that this weekend," Tomlin said. "Knowing him, I know he will do what's necessary."
