The Steelers moved to address a vital empty spot on the roster by re-signing the player who has done it well enough to remain virtually invisible his entire career. The Pittsburgh Steelers announced in an official press release today, they have re-signed veteran long-snapper Greg Warren, who has been with the team since signing with them in 2005 as an un-drafted free-agent out of North Carolina University. Warren has been solid as steel during his career in Pittsburgh. For a NFL long-snapper, the ultimate achievement is to go unnoticed and keep your job. Warren has remained virtually invisible.
