PITTSBURGH -- The Pittsburgh Steelers have invested heavily in the secondary the last few years and still appear to have depth issues.
Their third cornerback this preseason has been a safety, rookie Sean Davis. The Steelers would like to sign Keenan Lewis but have not because of his lingering groin/hip issues.
But with 15 days before the opener at Washington, the Steelers are experimenting with lineup changes in practice.
On Sunday, the team worked this group together, according to defensive coordinator Keith Butler: veteran William Gay in the slot, safety Robert Golden moving to inside linebacker (which he did at times last year in the nickel package), Davis at safety alongside Mike Mitchell and first-rounder Artie Burns on the outside alongside Ross Cockrell.
