The upcoming matchup between the undefeated Pittsburgh Steelers and Los Angeles Chargers marks a significant clash of two top defenses, with both teams boasting a 2-0 record. Steelers coach Mike Tomlin emphasizes a physical style of play, although concerns about the offense's consistency persist, particularly with quarterback Justin Fields filling in for Russell Wilson. Conversely, Chargers coach Jim Harbaugh has seen his team thrive defensively, leading the NFL in points allowed per game and showcasing running back J.K. Dobbins' impressive performances. This game is notable as it features two of the league's leading defenses, with the Steelers allowing an average of eight points per game. Analysts predict a close game, with some favoring the Chargers due to their offensive capabilities, particularly with Justin Herbert at quarterback. The outcome could hinge on which offense can effectively navigate the opposing defense's strengths.
