This is an interesting addition but not likely a significant one. Even though the Steelers' quarterback group could undergo change, Smith would be fighting for the No. 3 job.
Byron Leftwich, who is also a free agent, is expected to re-sign and become the primary backup to Ben Roethlisberger. Leftwich broke his arm in the preseason and spent the entire regular season on injured reserve.
That's why Smith's best shot at sticking with the Steelers is winning the third-string job. Smith, a Heisman Trophy winner who was with the Ravens from 2007 to 2009, spent last season with the United Football League's Omaha Nighthawks. He failed to establish himself as an NFL starting quarterback because he struggles with accuracy.
