As the Pittsburgh Steelers prepare for training camp, the competition for the 53-man roster heats up. Among those on the roster bubble, wide receiver Ben Skowronek stands out for his punishing run-blocking skills and contributions on special teams. Rookie safety Sebastian Castro, despite being an undrafted free agent, is seen as a potential foundational piece for the future of the secondary. Defensive tackle Dominique Davis is also under the spotlight, as the Steelers look to improve their run defense and bolster their line with strong nose tackles.
