The Pittsburgh Steelers are entering a new era as they head into the 2026 season, with Mike Tomlin departing as their head coach. One player who could be key to Pittsburgh's defense in the 2026 season is defensive tackle Derrick Harmon, as Fox Sports named him a potential breakout player. In his rookie season, Harmon finished with 27 total tackles, a tackle for loss, three sacks, a pass deflection, and a fumble recovery. Despite being 37 years old, Heyward is still one of the best defensive tackles in football. In the 2025 season, Heyward finished with 78 total tackles, nine tackles for loss, 3.5 sacks, six pass deflections, and a forced fumble.
