Cam Thomas is currently penciled in as the Steelers' starting left end. Thomas was a 3-4 nose tackle with San Diego last year, but the Steelers plan to use him at five-technique end opposite Cameron Heyward. Still only 27 years old, Thomas offers some upside as a two-gap lineman whose primary responsibility will be run stopping. He likely won't play on passing downs. The Steelers lean on their linebackers and Dick LeBeau's zone blitzes to create pressure.
