Steelers defensive rookies tend to watch and learn.
Troy Polamalu, Ike Taylor, LaMarr Woodley and Lawrence Timmons all had a minimal impact in their rookie year.
It wasn't always this way.
In 2001, the Steelers drafted Casey Hampton in the first round and Kendrell Bell in the second round. Hampton started the last 11 games at nose tackle and was a mainstay there for the next 11 years. Bell had nine sacks as a rookie, although his career was cut short by injuries.
The Steelers are long overdue to draft a defensive player who can start right away. Specifically, they need a pass-rusher to replace James Harrison.
Jason Worilds is in line to replace Harrison at outside linebacker. That doesn't make opposing quarterbacks shake in their shoes. He has 10 sacks in three seasons, but he doesn't have the presence that Harrison had.
Look for the Steelers to take a pass-rusher early in the draft, and for that pass-rusher to beat out Worilds for a starting job.
Then it just becomes a question of who. In 2012, Jarvis Jones of Georgia led the nation in sacks with 14.5, tackles for loss with 24.5 and forced fumbles with seven. However, his spinal stenosis might scare some teams away.
Jones could be available to the Steelers at No. 17. If he is, they'll have a decision to make after weeks of poring over Jones' medical tests.
If the Steelers don't get Jones or take him off their board because of medical concerns, they'll need to look elsewhere for a pass-rusher.
Oregon's Dion Jordan will be off the board by the time the Steelers pick. BYU's Ezekiel Ansah is too raw. LSU's Barkevious Mingo is too inconsistent.
Damontre Moore of Texas A&M could be on the Steelers' wish list. He had 12.5 sacks last season and goes to the Steelers in Pat Kirwan's mock draft on NFL Draft Scout.
There will be a learning curve for whoever the Steelers draft to fill the void at outside linebacker. He'll be learning, just not watching.
