The Steelers front office and coaching staff didn't shut off the lights and go home when they made their last selection in the 2013 NFL draft.
After the draft, the Steelers signed those undrafted free agents, and they likely were on the phone with many of them before the draft was over.
Even before the seventh round, teams normally begin calling players expressing their interest in signing them if they go undrafted, according to NFL.com.
When Mr. Irrelevant's name is announced, the mad dash to sign undrafted free agents begins.
Ed Bouchette of the Pittsburgh Post-Gazette once compared the process to a game of "musical chairs."
Every once in a while teams can find hidden gems in undrafted free agency. James Harrison and Willie Parker were undrafted free agents. So was Donnie Shell, who's third on the Steelers' all-time list with 51 interceptions.
Even if none of the following names ring a bell, chances are at least one of them will become a household name for Steelers fans.
