In their Week 1 victory over the Atlanta Falcons, the Pittsburgh Steelers showcased a strong defensive performance, highlighted by interceptions from newcomers DeShon Elliott and Donte Jackson. The Steelers' secondary, which had been a concern, effectively contained Falcons quarterback Kirk Cousins, limiting him to just 137 passing yards and a passer rating of 59.0. Offensive rookie center Zach Frazier made a significant impact despite a shaky start, allowing no pressures during pass protection and excelling in the run game. Veteran presence was crucial for the secondary's success, as noted by head coach Mike Tomlin, who praised their communication and energy. Meanwhile, T.J. Watt's disruptive performance included a fumble recovery and a crucial sack that sealed the win. The Steelers' defense, bolstered by offseason acquisitions, is trending positively heading into future matches.
