The Pittsburgh Steelers wouldn't have six Lombardi Trophies if it weren't for contributions from undrafted players.
There might be a lot of hype surrounding the NFL draft, but as soon as Mr. Irrelevant's name is called, the frenzy to sign undrafted players begins.
A lot of teams round up more undrafted players than drafted players. The Steelers signed 15 undrafted players this year and drafted nine.
Some undrafted Steelers are worth keeping an eye on. The next Willie Parker or James Harrison could be among the Steelers' 2012 and 2013 undrafted classes.
